Business Calculus Preparation

Hello everyone, I will officially be transferring to CSULB this upcoming fall. I’m a bit nervous because of the fact I will neee to take business calculus my first semester. My math/algebra skills are not where they should be. I tried taking college algebra but I had to drop it. I’ve received an A in both intermediate algebra and elementary statistics. This is my most recent math background. I know I need a decent algebra background in order to be successful in business calculus so my question is,

What exact topics in algebra should I try and master over the summer to minimize struggling in the course? Please be specific and include all the topics you can think of, and if you can include a link or website that will help with the topics. I really appreciate it. Thank you.
