I use a proven 4-part method that helps students build speed, accuracy, and true confidence:

1. Strategy – Learn how to break down problems and navigate each section efficiently
2. Content – Identify and fill knowledge gaps through personalized lessons
3. Practice – Apply what you’ve learned through targeted drills and full-length exams
4. Repetition – Reinforce mastery until weaknesses become strengths

If you're serious about reaching a top score and want to work with someone who’s done it and helped others do the same, I’d love to help. I work with students across all ability levels and tailor every lesson to each student’s unique goals.

ACT Math

ACT Math

I scored a perfect 36 on ACT Math and specialize in helping students improve their scores by 6–8+ points through personalized, high-impact prep. My approach goes beyond content review—I teach students how to treat the ACT like a game, focusing on strategy, timing, and muscle memory. With over 7 years of experience, I’ve worked with students across all levels—from those aiming for a 30 to those pushing from 34 to 36. Together, we: - Identify content gaps in algebra, geometry, trig, and data analysis - Create a custom formula sheet for rapid recall - Build speed and confidence with timing drills and pacing strategies - Use real ACT practice tests to simulate pressure and sharpen execution - Review only the most high-yield problems that consistently show up This method has helped many students secure scholarships and gain admission to top universities. Whether you're targeting your first 30 or your first 36, I’ll help you get there efficiently and confidently.
ACT Science

ACT Science

I scored a perfect 36 on the ACT Science section and specialize in helping students improve their scores by 5–7 points through personalized, strategy-based prep. Contrary to what many expect, ACT Science doesn’t test science knowledge—it tests how well you reason through graphs, data tables, experimental design, and scientific arguments under time pressure. My method is built to master exactly that. Here’s how I help you succeed: - Pattern recognition: You’ll learn the 3 recurring passage types and how to approach each with confidence - Time control: We’ll master pacing, including when to skim, when to dive in, and when to guess - Strategy drills: We’ll practice identifying controls, variables, trends, and flaws in experiments quickly - Targeted review: For students who struggle with background knowledge, I cover the minimum science context ACT expects This test is about efficiency and logic, and I will give you the tools to think like a scientist—even if you don’t love science. Most students raise their score substantially within just a few lessons.
