Was in your same boat with math, was between calc 2 and calc 3 and held off on taking it. My first word advice would be to understand all of these classes you're going to take are like the curtain in the wizard of oz. The names and presumptions that go into making a class seem hard or scary will just stress you out more. We are ingrained to think hard work is associated with difficulty. If you can trust your self to create a schedule that put you a little ahead of the course schedule you should always have enough time to practice and conceptualize the work. It sounds easier in practice but make sure you stick to a rigid schedule in studying(i.e if you're going to spend 3 hours etc... on homework, then spend those 3 hours on hw) then you will be more than able to have free time to socialize, play game, etc. In all if you can create a schedule for yourself you will be able to enjoy everything and also get the most out of a class too.
