You’re from Texas, right? Are there any state schools on your list? You indicated that you need financial aid, so the first thing you have to do is find a couple of safeties (schools you’re sure to get into, can afford, and would be happy to attend). These schools usually have admit rates closer to ~40% than ~10%.
How much can your parents afford to pay? You won’t be able to get enough outside scholarships to pay for tuition, room, and board. Colleges determine need and many will subtract the amount of outside scholarships from the amount of your need and reduce their grants by that amount. For example, say they determine your need is $20k/year and offer you a $10k scholarship (most don’t meet need) and you get an $8k outside scholarship. They’ll subtract the $8k from the $20k and your new calculated need is only $12k. Because your need is less, they’ll reduce your $10k grant – maybe by a few thousand or maybe by the whole $8k – so your net cost won’t change.
If your parents can afford the apps, having a couple match and reach schools is fine. Just make sure to line up your safeties first.
