Well,... There are several things to consider:
- Homework: check how much time you have left. Evaluate which items re the most important. Do what you can, without killing yourself in the process. You might want to keep a journal of your progress.
- Your supervisor: contact (or ask your mom to contact) someone to discuss these issues. You may ask advice from a teacher you like.
- Other school: you can't do anything about it, so just relax
Good luck
