I need help with my future

Sorry I’m new to the forum and I don’t know if this is the right thread to post this but I plan to attend Texas A&M as an out of state first time undergrad student after my senior year of high school. Currently, I am a junior. Their aerospace major looks pretty amazing.

I seriously need to raise my act scores to be admitted to Texas A&M with scholarships. So I wanted to know how I could raise it. I know that practice is key but I do not know what to buy or if there is free practice materials or anything else out there which will help raise my score.

Also what are my chances of being accepted into the college?

What should I do more in order to get scholarships.

Getting a better score on the ACT is necessary for you just to assure admittance, let alone get a scholarship. What does their site say about scholarship opportunities? There are many ways to prepare for the ACT. Research online the best ways for you in your area and then do that. Good luck.
