@Mercurrii…PRACTICE with an adult. Have them ask you the questions. Even with Mom or Dad it would be awkward enough to adjust.
Your personal LGTQ+ story could be helpful if well developed.
The “I used to” and “I am going to” resume items are not helpful, and possibly slightly harmful. Violin since 6th grade (with an aim of continuing in BS) IS helpful. Those types activities will need to be your push. Study up on the programs the schools offer in the areas of your interest. Show you have put in the time learning about the individual school programs and classes.
These BS are as much about the people, community, and engagement for the student body vs academics. Your resume is just “OK” and that fine. Your sell will have to be you.
Plenty of Student Council presidents with perfect SSATs will be rejected. You are not out of the running. You have to figure out how you are the missing puzzle piece to the new class.
And study for your SSATs. You are aiming high for the BS list, so you also need 90th % + to get into the maybe pile.
Again, trying to be honest and helpful. Feel free to PM any specific Qs. I am here to help. It is a long and hard process.
