SAT/ACT small group · winter bootcamp
Small-group SAT/ACT prep with a named teacher, and AI practice a person checks.
Four weeks, eight live hours, four to six students, one exam and one level per group. Live online for families anywhere in the US, run from Glenview, Illinois. The student leaves with an AI agent they built, a study helper with written rules, and keeps it; the teacher leaves nothing to a tool.

How a session works
Teach, practice, check, retry. The written rule is on the screen the whole time.
A session is not a lecture plus an app. The teacher works the pattern, the student practices on original material, a person checks what the agent produced, and the student re-runs the pattern under time. The agent is a helper that runs on rules the student wrote; here is the kind of rule it runs on.
- 01
Teach
The teacher works one question type out loud: what the question is really asking, where the trap sits, and what a solid answer looks like.
- 02
Practice
Original practice items, never official test questions. Each miss goes into the student’s own error log, and the agent builds the next practice block from that log.
- 03
Check
A person checks the agent’s output before it counts. When the tool is wrong, and it sometimes is, the wrong answer becomes the lesson rather than a note to skip.
- 04
Retry
The student re-runs the same pattern under time. The log records what changed, and that record belongs to the student after the group ends.
The student’s written rule, read by the teacher
Using my error log, quiz me on the two patterns I missed this week. One at a time. Do not show the answer until I commit to one, then make me explain why in one line. Never give me a question from a real test.
The agent does not know your student and does not remember last week. The error log carries that, and the log belongs to your family. It drafts practice; a person checks it.
Watch the check step catch a wrong answer
Watch the study system work — mistake, instruction, check.
This is the loop your student runs in every subject. The part most programs hide — the instruction — is the part we teach.

Three files, one habit — the loop every subject here runs on
## Reading & Writing — Oct 3
- Q14: comma splice vs. period+capital.
Picked B. Right answer D.
Why: I treat "however" like "and."
Written by the student — readable by you
Using my error log, quiz me on comma splices and "however" sentences. One at a time — don’t show the answer until I commit, then make me explain WHY in one line.
The other option
1:1 SAT/ACT tutoring, four sessions at a time.
Four one-hour sessions with a practice plan and a progress recap, taught by Jinwoong Lee in his spare hours only. It is the right choice when the group’s dates do not fit, or when one section needs the whole hour. Pricing differs by package; the consult decides which fits, and you get the terms in writing.
Who teaches
Every session is taught by Jinwoong Lee.
UC Berkeley 2018; eight years building software at companies that include Amazon and Ring; eleven years in private education, including more than ten years of college consulting and SAT/ACT prep; 80+ placements at top-20 universities. If a section ever needs a second teacher, that teacher is named before you pay, not after.
About JinwoongWhat it never promises
The things we will not say, in writing.
- No score promise. Variability between students is large, and anyone promising a number is guessing.
- No official test questions in any tool, prompt or demonstration. Original practice material only.
- No pooling of SAT and ACT students to reach a minimum. One exam and one level per group, or the group does not run.
- No seat sold before the written minimum-enrollment date, and no deposit taken before the refund terms are published.
- No claim that a model knows or remembers your student. The student’s written page carries the continuity.
Is this cheating?
AI explains, quizzes and organizes. It never writes what the student submits. A parent approves the tools, and where a teacher’s rule forbids AI for an assignment, it is off for that assignment.

Tell us the exam, the grade and the dates that work. We reply with whether the February group fits, or whether 1:1 sessions or the summer bootcamp are the better answer.
No score promise, no official test questions, no seat sold before the written minimum date on February 15, 2027.
