Anatomy and Physiology

Starts

Hey! If you are interested in learning about the human body feel free to join this session. We are gonna cover each body system in depth starting with the nervous system and ending with the reproductive. I am a firm believer that learning is easier and funner especially science with a group of people. Honestly expect this to be a chill interactive session about general overall anatomy! If we fail to cover anything that you guys would like I would love to add more sessions

AP Biology Summer Prep!

Starts

Each week, we will review essential background information to help you better understand each unit. This approach serves as an excellent refresher for those who haven't recently taken a biology course or wish to strengthen their understanding of key concepts. Especially if you haven't taken either Biology or Chemistry!
We will go over: Organic Compounds (monomers and polymers), Cell Transport, Protein Synthesis, Basic Cell Division, Basic Genetics, and Natural Selection to give you a sturdy foundation for AP Bio next year!

AP Biology Summer Crash Course

Starts

AP Biology is a challenging course! This AP Biology Summer Crash Course is a comprehensive review designed to cover the entire AP Biology curriculum in depth. Across 20 sessions, students will review all 8 AP Biology units in a two-session-per-unit format, plus 2 dedicated sessions for Free Response Question (FRQ) strategy and practice.

Each 90-minute session includes:
1. Targeted concept reviews aligned with College Board’s course framework
2. Guided practice with AP-style multiple-choice questions (MCQs)
3. Skill-building in data analysis, graph interpretation, and experimental design
4. Walkthroughs and breakdowns of sample FRQs (in the last week)
5. Test-taking tips, exam strategy, and study resources

By the end of the course, students will have a basic understanding of all major topics and have built the confidence and skills necessary to succeed in their AP Biology class when school starts!

Pre-AP Biology Introduction (recommended for self-studiers)

Starts

Occasionally throughout summer, I will go over several different tips and tricks you should know before going into AP Biology and tricks that I used to earn a 4 after self-studying the entire course without a teacher. I will also go over specific things you should remember from your introductory biology course and go through practice problems as well.

AP Biology Bootcamp

Starts

Over the next 9 months leading up to the exam, we'll be covering each of the 8 units in the AP Biology curriculum across the time we have together. With monthly sessions held during the first week of each month, we'll spend time giving you in-depth explanations of all the concepts you'll need to grasp by your exam while also providing plenty of resources, notes, and additional office hours throughout the rest of the month. These extra sessions will be open for questions, extra review, or anything biology related, so don't hesitate to reach out! This series is open to learners taking AP Biology this year or just anyone curious to learn more. Our sessions are solely based on accommodating to your needs to help you succeed, so we hope you'll join us!
