Hi All! I am a rising senior who received a 4 on the AP exam and am excited to start my 4 day crash course with you all. The purpose of this short course is to teach the most important topics in a summarized but clear way so that you all can be ready for the first few units of AP Bio and guide you through the class. Be ready to actively engage with me and other students so that we can build fun and engaging sessions!

AP Biology Bootcamp

2nd session

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!
