If you're looking for an organised and professional teacher to help you achieve your academic goals, look no further! The IB science subjects can be extremely difficult to go through on your own, and I'll be glad to use my experience to help you out.

A couple of things I like to do:

- Initial test or interview to assess your level.
- Use Notion as a platform to share all my resources.
- Use mock papers that lay out the exercises JUST like in the real exams, so you will feel really prepared.
- I give homework when appropriate.
- I provide any kind of mentoring and college counseling. People who study Biology and Chemistry usually want to pursue a clinical career-- and that is a complex process!
