Do not know what school level you are returning to, but may I suggest a strategy to help combine your interests with some of the necessary school work, e.g. papers etc.

Find a way to use whatever subject you are studying to enhance your knowledge of survival. For example:

If you have to do a history research paper, select a topic related to survival, for example, How Shackelton and his men survived: what they did right, wrong etc.

Use math to calculate calories required vs weather vs activity to determine how much must be consumed for how long.

Use English studies to read and report on stories of survival, both real and fictional, and what realistically would work and what would not.

It may make you feel that your studies are less academic and more real world.

Good luck in school.
