How it works

A simple path to higher grades & scores

No bloated programs. Three steps, and every session moves a metric that matters.

1

Free diagnostic consult

A 20-minute call plus a short problem set to pinpoint whether the issue is content, exam strategy, or problem-solving habits β€” most students are surprised by the answer.

2

Targeted 1-on-1 sessions

60-minute live sessions built around your gaps. We work problems together on screen, then I assign a custom set so the concept sticks before next time.

3

Practice, review, repeat

We track your accuracy by topic in a shared doc and re-test weak areas with exam-style problems until they're strengths. Watch the grades and scores climb.

Pricing

Straightforward plans, no surprises

Every plan includes session recordings, custom problem sets, and between-session chat support. The free consult comes first β€” always.

About your tutor

Hi, I'm Charlie.

I scored a 132 on the MCAT's chemistry/physics section and have spent the last several years helping students turn chemistry from their weakest subject into their strongest β€” from AP Chemistry to college organic to MCAT prep. I tutor chemistry full-time β€” not as a side gig between classes.

My approach is simple: chemistry exams don't reward encyclopedic knowledge, they reward pattern recognition under time pressure. I teach you to see the handful of moves every test recycles, do the math fast, and walk in confident instead of hoping for easy questions.

Chemistry tips that actually move the needle

A preview of the strategies we drill in sessions.

🧠 Learn mechanisms as electron-pushing patterns

There are only a handful of arrow-pushing moves on any exam. Master nucleophile-attacks-electrophile, proton transfers, and leaving-group departures, and 80% of orgo questions become recognition, not recall.

πŸ“ Dimensional analysis beats memorized formulas

Most chemistry calculation questions can be solved by tracking units. If your units work out to the answer's units, your setup is right β€” this saves you on test day when a formula slips your mind.

⏱️ Know what you're solving before you start

Long problems and science passages are dense by design. Skim the questions first so you know which figures actually matter β€” then mine the problem for exactly that data and move on.

πŸ” Spaced repetition for high-yield facts

Amino acid structures, pKa values, periodic trends, solubility rules β€” these are pure points if you drill them on a spaced schedule instead of cramming the night before.

FAQ

Questions, answered

Anything else? Ask in the contact form below.

All sessions are live on Zoom (or Google Meet, your choice). I share my screen to work problems step-by-step, and you get the recording plus written notes afterward. All you need is a laptop and a notebook.

General chemistry, organic chemistry, and biochemistry β€” for AP Chemistry students, college students (Gen Chem I/II, Orgo I/II, Biochem), and the chemistry portion of the MCAT. That's the full scope: if it's chemistry at one of those levels, I cover it.

Absolutely β€” that's the most common starting point. We'll rebuild from first principles (the mole, bonding, basic algebra for chemistry) before touching exam-style problems. Students starting from scratch typically need the Score Booster plan.

No. I provide all practice problems, summary sheets, and problem sets. If you already own a textbook, an AP review book, or MCAT prep materials (Kaplan, Princeton Review, AAMC), we'll integrate them β€” but nothing new is required.

No honest tutor can guarantee a grade or score β€” it depends on your effort too. What I can share: most of my students improve a full letter grade, and my MCAT students' median gain is +5 points on the C/P section. If after the first paid session you don't think it's a fit, I'll refund it in full.

Life happens. Reschedule or cancel free of charge up to 12 hours before a session. Inside 12 hours, the session is charged at 50%.

Yes β€” small-group sessions (2–4 students) run at $35/hr per student, and I offer 2-week crash courses before AP exams, college finals, and MCAT test dates. Mention it in the contact form and I'll share upcoming availability.
