i know it's expensive, and my family doesnt support it, and it's kinda hard to apply for financial aid as a international student, i know the policies pretty well, because i have been searching details online for a while now, the thing i am worrying about

Well, if that's a requirement, you'll have to make it your thing and beat it. You can do it. Math was never my thing either, but I did what I had to do. I figured it out, plowed through it, then immediately forgot it. I actually hated math, but once I really worked at it and started to figure it out I kind of liked it. Mainly because I was making it my bitch and view many, many things as competition. Don't let some stupid math defeat your dream. Also, I would reconsider skipping pre-calc if possible. Get some foundation.
