So my brother goes to Michigan and is in his senior year there and I’m only a sophomore in highschool and just finished my 1st sem and did pretty bad do I have a higher chance of getting into UofM and he might get a job working for UofM to.
Regardless of any legacy hook, which is doubtful, if you keep doing “pretty bad” you will not get into Michigan. Concentrate of your schoolwork.
Chances - 0%.
You have to be a competitive candidate.

If your around these numbers then Legacy might be helpful. You have to show interest and have a great essay.
Concentrate on your school work and talk to your teachers on what you need to improve. Then do that. Get help now. It will pay off later.
