[{aspiring_to_clarity}]

I believe the key to success in Math and Sciences for people who've been out for a while or are not naturally inclined is finding a good teacher who can explain things in a way you understand. This is often hard because the people who teach these subjects usually don't seem to understand how someone can just not get it. I would try to get in touch with some other students to learn about teaching styles of particular teachers. If you already have your classes set, then think about a tutor. They can take more time to one on one with you through the tougher concepts.

Good luck. I am glad to see someone pursuing their dream.
