Hi everyone, this past year I took calc 1 and 2. I loved taking these classes and I did extremely well in both. I especially loved doing problems like partial fractions and trig sub in calc 2, stuff that requires heavy algebra.
I haven’t done any math this summer and a sometimes when I scroll through this sub I realize I’m quickly forgetting stuff that I knew extremely well just a couple of months ago. I’m also definitely going to be taking calc 3/ differential equations in the future and I want to make sure I also do well in those classes.
Im wondering if anyone has any recommendations for websites that will allow me to keep my skills sharp without having to go through a whole online course. I don’t know if anything like this exists but I figure it probably does. I also want to do some problems just because I also find it pretty fun so do so. Does anything like this exist for a girl like me?

Hi everyone! I ride this schwinn (26” tires) to work, it’s a short ride but it includes about a 1/2 mile steep hill on the way home. I work at night and I sometimes get off work at like 2am, by then I’m so tired and slow climbing up the hill.
I’m looking to add a little bit of power to my bike to assist me with this hill, nothing too crazy and I probably won’t always use it, just when I really need a boost for the hill. I’m very new to bikes and I really need some help with what conversion kit to select, obviously I’d love to buy a new e-bike but my budget maxes out at around $500.
Ideally I’d love to take my bike to a shop and have someone more knowledgeable assist me with the build, but there doesn’t seem to be any shops that actually work with conversion kits. Hoping I could get some good advice on this sub, thanks everyone :)
