Helping students truly understand Math and Physics
StudyBAP provides structured, high-quality learning resources for high school students — free lessons, practice worksheets, and clear explanations designed to build real understanding.
Making difficult concepts genuinely clear
Our mission is to help every student move from confusion to confidence. We do that through carefully sequenced lessons, worked examples, guided practice, and downloadable resources — all designed to support independent learners, classroom students, and anyone preparing for exams.
What students can find here
StudyBAP is built around structured course content — not just isolated videos or random worksheets. Each unit follows a clear progression:
Structured lessons
Each chapter includes a full lesson with vocabulary, worked examples, and guided problems — so students understand the concept before practicing it.
Student workbooks
Downloadable PDF workbooks accompany every chapter, giving students a printable resource they can use alongside the lesson.
Independent practice
Problem sets designed to reinforce each concept with increasing difficulty — ideal for homework, review, or self-study.
Exit tickets & quizzes
Short assessments at the end of each lesson and chapter help students check their understanding before moving on.
Answer keys
Full answer keys are included so students can check their work and learn from mistakes independently.
Current subjects
StudyBAP is actively growing. Here is what is available now and what is in development:
11 units covering the full Algebra 1 curriculum — from foundations and linear equations through quadratic functions and statistics. This is the primary completed course on StudyBAP.
12 units covering functions, trigonometry, analytic geometry, sequences, and introductory calculus concepts.
Course structure and unit outlines are in place. Full lesson content is being developed and will be added progressively.
About the educator
Sang Lee
Founder & Educator, StudyBAP
Sang Lee is a mathematics educator with a passion for making rigorous concepts accessible to every student. StudyBAP grew out of years of classroom teaching and tutoring experience — and a belief that the right explanation, at the right level, can unlock understanding for anyone. The Sang Real Math YouTube channel extends that same approach to video lessons covering Algebra 1, Algebra 2, Precalculus, and AP Calculus BC.
Sang Real Math on YouTubeOur values
Clarity first
Every lesson is written to be understood, not just read. We break concepts down to their core and build back up with worked examples.
Structured progression
Topics are sequenced so each concept builds on the last. Students never feel lost because we never skip the foundations.
Practice that sticks
Understanding is built through doing. Our worksheets and problem sets are designed to reinforce concepts and build lasting confidence.
Free and accessible
All lessons, workbooks, and practice materials on StudyBAP are free. Whether you're catching up, keeping pace, or pushing ahead — we meet you where you are.
