I drop a neodymium magnet into the 4-foot copper pipe. Thirty seconds later, it still hasn’t emerged from the other end.
“How is that possible?” one of my students asks. I explain Lenz’s Law: the object’s descent induces an opposing magnetic field in the pipe that slows its fall.
Through designing and teaching physics lessons, I now think of myself as a physicist author, forging new words and coming closer to understanding the inner workings of the world.

Traditional consulting
×One assigned advisor, take it or leave it

×Minor grammar edits, missing the forest for the trees
×The same generic playbook handed to hundreds of clients

The Word List That Actually Moves Your Reading Score
This isn't a stack of flashcards to memorize. We rank the words that actually keep appearing on the College Board SAT Test Suite Bank, and we drill their secondary meanings—especially the scientific and technical verbs (“subsume,” “advance,” “survey,” “exploit”) that trip up strong readers because the everyday meaning is a trap. Learn how the test uses the word, not a dictionary definition.

The Traps, Named
The 30 English Traps the College Board Sets
College Board 在英语部分设下的 30 个陷阱
These are the exact patterns our 15-week course trains you to spot in seconds. Tap any trap to see how it works.
01Extreme language›
Options with always, never, all, or none overstate what the passage actually says. The measured choice usually wins.
02Half right, half wrong›
One half of the sentence matches the passage, the other quietly contradicts it. A single wrong clause kills the whole answer.
03Out of scope›
The statement is true in real life but was never established in the text. Only what the passage supports counts.
04Deceptive paraphrase›
The answer reuses the passage's exact words but flips or shifts the meaning. Match ideas, not vocabulary.
05The opposite answer›
It states the reverse of the passage. Misreading one word (not, but, however) makes it look right.
06Too broad›
A sweeping generalization the passage only partly supports.
07Too narrow›
A single true detail offered as the main idea the question actually asked for.
08Right answer, wrong question›
A true statement that simply doesn't answer what was asked.
09Unwarranted comparison›
Claims one thing is more or less than another when the passage never ranks them.
10Correlation as causation›
Turns “is linked to” into “causes.” The SAT loves this jump.
11Words in Context bait›
The choice fits the general topic but not the precise nuance the sentence needs.
12Detail dressed as main idea›
A vivid, memorable detail posing as the passage's central point.
13Secondary meaning›
A common word used in an academic sense (qualify, advance, subsume, sustain) where the everyday meaning is the trap.
14Tone mismatch›
The answer sounds too excited or too harsh for an author who is measured or neutral.
15Distortion of degree›
“Some” becomes “most,” “suggests” becomes “proves.” The strength of the claim is off.
16Command of Evidence›
The quoted line looks relevant but does not actually prove the claim it's paired with.
17Graph and table misread›
Wrong axis, wrong units, or the trend read backwards. The data trap in Quantitative questions.
18Weak vs strong support›
A fact that loosely relates versus the one that directly backs the claim. “Best supports” means most direct.
19Pronoun–antecedent›
The pronoun that sounds fine but doesn't clearly and correctly match its noun.
20Subject–verb across a phrase›
A plural noun sits next to the verb and tempts the wrong verb number. Find the true subject.
21Misplaced modifier›
The opening phrase must describe the noun right after the comma, or the sentence says something absurd.
22Comma splice bait›
Two complete sentences joined with only a comma, offered as the “smooth” choice.
23Homophone traps›
its vs it's, their vs there vs they're, whose vs who's — they sound alike and are tested constantly.
24Faulty parallelism›
Items in a list or comparison that don't share the same grammatical form.
25Verb tense drift›
A tense that shifts for no reason within the passage's timeline.
26Redundancy›
The choice that repeats an idea already stated. On the SAT, shorter and non-repetitive usually wins.
27Rhetorical synthesis›
Ignoring the goal stated in the bullet notes and picking the sentence that merely sounds fluent.
28Transition reversal›
The ideas continue, but the trap inserts a contrast word like however or yet (or drops one you needed).
29Illogical completion›
An ending that's plausible in general but isn't supported by the specific setup of the sentence.
30Essential vs nonessential›
which vs that and the commas around a clause: whether the information can be removed changes the punctuation.
The Test-Maker's Desk
Watch a Real Question Get Dismantled, Choice by Choice
站在出题人的角度,逐一排除三个错误选项
College Board writes one right answer, then builds three decoys by breaking exactly one link each. We teach students to read the way the writer wrote. Press play and watch the logic do the work on a real 1550-level question.
Reading & Writing · Command of EvidenceQuestion 13
Neurobiologists Laura Cuaya, Raúl Hernández-Pérez, and colleagues investigated the language detection abilities of eighteen dogs of various ages. The researchers monitored the brain activity of Maverick (a 117-month-old border collie), Mini (a 126-month-old mixed breed), and other dogs while the animals listened to three recordings: one of The Little Prince being read in Spanish, the second in Hungarian, and a third made up of short, randomly selected fragments of the first two, scrambled so that they didn't resemble human speech. Each of the dogs was familiar with either Spanish or Hungarian, but not both. The team concluded that the younger the dog, the worse it may be at differentiating between familiar and unfamiliar languages.
Which finding from the study, if true, would most directly support the team's conclusion?
Variable 1 · AGEyounger ↓
must move together
Variable 2 · THE GAPfamiliar vs unfamiliar response ↓
A
As the age of the dog scanned decreased, so did the amount of brain activity in response to hearing the language the dog was accustomed to or the other language, but not in response to hearing the scrambled recording.
Trap 08 · Right answer, wrong questionMeasures how much activity, not the gap between the two languages
B
The similarity between the pattern of brain activity a dog showed in response to hearing the scrambled recording and the pattern it showed in response to hearing the language it was not accustomed to was lowest among younger dogs.
Trap 09 · Unwarranted comparisonWrong pair: scrambled vs unfamiliar, not familiar vs unfamiliar
C
Dogs showed a different pattern of brain activity when hearing the language they were accustomed to than when hearing the other language, and the difference in brain activity decreased as the age of the dog scanned decreased.
Both links intactVariable 2 (the gap) · Variable 1 (age) · same direction
D
Although the dogs' general hearing sensitivity declined with age, dogs of all ages showed more brain activity in response to hearing the language they were accustomed to than in response to hearing the other language.
Trap 01 · Extreme language"All ages" erases the age trend; "hearing sensitivity" is scenery
Ready. Six moves, about thirty seconds. Tap any step above or press play.
Move 1 · Decode the claim before touching the choices. A "support" question is a contract. The conclusion has two variables and a direction: as age goes down, the gap between a dog's response to its own language and the other language goes down. The right answer must deliver both, in that direction. I build three decoys by breaking one link each.
Move 2 · D breaks the age link. I wrote "dogs of all ages" so the gap is identical at every age. If age changes nothing, the finding cannot support "the younger the dog, the worse." The hearing-sensitivity clause is scenery: it makes you feel the word "age" without giving you an age trend in the thing that matters.
Move 3 · A breaks the gap link. I kept the age trend, then swapped the measure. "Accustomed to or the other language" lumps both languages into one pile of total activity. Less activity overall says nothing about telling the two apart. The scrambled clause is there to sound precise. Precision is not relevance.
Move 4 · B swaps the pair. The conclusion compares familiar vs unfamiliar. B compares scrambled vs unfamiliar, a pair the passage really mentions, so it reads as on-topic. Recycled passage nouns are my favorite bait. Wrong pair, dead answer, no matter what "lowest among younger dogs" says afterward.
Move 5 · C survives because nothing is broken. First clause: a different pattern for the familiar language than the other one, that is the gap. Second clause: the difference shrinks as age falls, that is the direction. Notice it is the plainest sentence of the four. No "all," no extra science. That is by design.
What this teaches.
1Convert the claim into variables and a direction before reading a single choice. Then every choice is a yes/no test, not a vibe.
2Each decoy breaks exactly one link. Find the break and stop reading; the rest of the sentence is decoration.
3Nouns recycled from the passage ("scrambled," "hearing") are bait, not evidence. Match the relationship, never the vocabulary.

The families who’ve been in the room, in their own words.
"Before I started high school, I was against finding a mentor because I'm only a 9th grader. Plus, I keep a daily diary and I feel pretty ambitious on my own. But my parents had received a referral from a close family friend whose son Collin tutored, and so I had no choice. As soon as I started working with Collin, I realized I had been completely in over my head..."
— Evan Choe—Peninsula High School, California
"I was ready to give up and go test-optional since not many students at my high school are college sweats, but my parents found Collin and he helped me join the Gilder Lehrman Student Advisory Council, win a Coca-Cola Scholarship, and boost my SAT score to 1530, the highest ever in my district. Collin even visited my hometown to help me write better essays!"
— Johnny Chen—Buckhannon-Upshur High School, West Virginia
Even though I was born in California, my parents moved me back to Shanghai, and I stayed until 9th grade. My English vocabulary and reading skills were behind as a result. But after one month of SAT English tutoring, and learning to summarize the patterns by getting inside the test-makers' heads, I scored a 720 in English and 1520 total. Now I have the scores I need to apply to the UCs.
— Mandy Ou—Gunn High School, California
"The most valuable part of Collin's service is combining the insight and ideas of 2,000 students' activities and essays from dream schools. I feel confident about my personal statement because it combines two of my hobbies: art and debate. Interdisciplinary strategy (交叉学科) makes me a more unique, appealing applicant. This would not be possible if I didn't read and model existing winners' examples."
— Jonathan Shu—Jesuit Dallas High School, Texas
"My daughter spent four days a week working with a big test prep company and made some progress but stuck in the low 1400s. We tried Collin and Connor's Lessons for the Most Missed Math Questions and could not be more thrilled with the result."

Work with Us
Succeed with Communication Skills. 高中生主动邮件联络找机会
The summer I applied, I wrote to nearly 10,000 people on LinkedIn. The replies did more than fill my activity list.
Nobody in my family had been through American admissions. I could not ask a cousin at Yale what worked. So I decided to ask strangers.
02 · 10,000 MESSAGES
I wrote to nearly 10,000 people on LinkedIn.
Current students, recent admits, professors, founders. Short, specific messages: who I was, what I admired about their work, and one question. Most never answered. Enough did.
03 · THE DOORS IT OPENED
Far more than essays and activities.
Those replies put me on the National GeoBee team, sent me traveling across the USA to meet the people behind the profiles, and handed me the essays and activity lists that became Essayfolio.
04 · WHAT YOU LEARN HERE
Cold outreach as a skill, not a gamble.
Which people to write to, what to say in three sentences, when to follow up, and how to turn one reply into a research spot, a recommendation, or a mentor for life.

We Turn Dream Schools into Daily Tasks

Every student in the room keeps a table like this one. The deadlines in blue are firm; the rest move. What never moves is the weekly line: one workshop, one email, one entry in the log. Small, finished tasks are how the ambitious stay ambitious.

What top schools actually charged our families.
Sticker prices now pass $100,000 a year. Most families on aid pay far less. These are the real 2026–27 award letters our families received, names removed, and the strategy that produced them.

Where families lose money
Wrong round
Binding Early Decision ends your ability to compare offers. NYU sent one family a $70,464 award from Stern and a Pell-only package from Tandon.
Messy forms
Home equity, a family business or a rental unit can count fully at one school and not at all at another. One field filed wrong can cost five figures a year.
No appeal
Yale and Williams both sent revised offers this spring after a second review. Families who never ask never see a revision.
Missed merit
McCabe, A.B. Duke, Robertson, Morehead-Cain: the biggest awards need nominations or separate essays months before RD, and most finalists must pass a merit scholarship interview.
Full Testimonial
Evan Choe
Peninsula High School, California · July 16, 2026
Before I started high school, I was against finding a mentor because I'm only a 9th grader. Plus, I keep a daily diary and I feel pretty ambitious on my own.
But my parents had received a referral from a close family friend whose son Collin tutored, and so I had no choice.
As soon as I started working with Collin, I realized I had been completely in over my head. I couldn't have possibly known the details and resources to get ahead. My friends have worked with upperclassmen debaters, and from what I've felt, Collin outclasses them all.
If I could rewind, I will tell the exceptional qualities I noticed about Collin that I'd want to know.
At the end of 8th grade, I won the Middle School Tournament of Champions in Policy Debate. This was my dream goal.
To help me reach this goal, Collin… worked with me for a weekend to apply for the University of Michigan 7-Week Summer Debate Camp, an activity I procrastinated before. He connected me with successful applicants who got debate scholarships at Emory, Harvard, and Northwestern, which helped me fit in and know more people at the camp.
Yes, I felt Imposter's Syndrome when one friend who had better grades than me was waitlisted. In fact, I was the only person in my year at Modern Brain, my middle school, to receive admission.
Work Ethic & Dedication: Collin is dedicated to my goals, and he will do whatever it takes to produce the highest quality before submission, including…
Growing Activities and Hobbies: I thought I was a great writer until I met Collin. As a history major himself, Mr. Hu is phenomenal at teaching lessons from successful applications, as I grew my hobbies in anime and art.
Time & Flexible Availability: …working overtime, staying up all night, being available at ridiculous hours, and even making himself available over holidays like New Year's Day to prepare debate files.
Perfectionism: This is a personality trait that I don't think Mr. Hu has any control over, but it benefitted me immensely. Knowing that the person I was working with had high verbal intelligence and could explain complex ideas in a clear, simple way provided a peace and comfort throughout the process, helping me stay motivated.
Role Model: Again, I didn't realize how little I knew about the process until Collin made sure we stayed on timeline. He set boundaries and I felt like I had to follow them. He was patient. I felt more hunger to work harder and think sharper. For example, Collin helped me cold-email local California Senator candidates to publicly post and verify my activities.
Also, even something as silly as asking the most lazy teacher for a letter of rec revealed how little I knew once I started receiving first-hand instructions.
Many of my friends in my year found other mentors, and throughout the winter, I heard mostly complaints from them. Seeing for myself the difference in quality from the people my friends worked with made me incredibly grateful, and it assured me that the person I was working with was truly special.
I want to conclude my own view of Collin with this: I definitely got lucky that my parents happened to discover Mr. Hu and not somebody else.
Please feel free to contact me for any more information.
