A quick bit about myself, I went to college for 2.5 years right out of high school(I ended with a 3.0 gpa), that was about 5 years ago now. I am now wanting to go back to college to finish my degree. My major back then was Business Management, however I have lost all interest in that field and would like to pursue a degree related to astronomy. Now to the hard part, I've not been good at math since middle school and any degree related to astronomy is grounded in math. This summer I will be taking college algebra, but I'm worried that even this could be too advanced for me and I would like to start preparing for the class now, but not entirely sure where to start. Should I review back into high school algebra and algebra 2, anything else I should go back and review? While I was in college I did take a college algebra level class and got a B, but I know I have forgotten a lot since then. In the fall semester I plan on taking trigonometry and an introductory physics class.
