What are my chances getting into UT Austin as a Neuroscience major?

Hi guys! I’m a senior at a high school in Austin who’s in top 10% of her class at a highly competitive non-ranking IB school. I know that UT’s automatic admission is for those in top 7%, so my application will be reviewed holistically. My SAT score is not at all that great, and I’ve taken it multiple times with the highest score being a 1370 (equivalent of a 30 ACT according to the testing agency’s concordance tables). I know, it’s a shame… but I’m not a good test taker. I am hoping to make my application look more enticing with great essays and extracurriculars like volleyball, math club, competitions, IB conferences that earned me scholarships, etc. I was wondering what my chances are of getting admission with neuroscience as my first choice major would be, and computer science as my second choice… Please let me know! Thanks!
