Going into college

Hello, I am going to attending my local community college this fall. I wondered how I could get a leg up on my peirs in math. I have taken up to Algebra 2. I was wondering if anyone had tips for making sure I have a solid base on Algebra. Anything I should be sure to have memorized or practiced (I know the Unit Circle is something I am memorizing). Also any tips or tricks for breaking my way into understanding (and getting a good grade in trig and calc). I dont take my first Trig class until Winter but is there anything I can do now to get a head start. Ill take any and all tips any one has. I really want to invest my time in understanding these concepts. I also relize I have a good amount of time to get some study, memorization, etc in. Thank you!
