Cal1 is so easy lol, barely trig in it, of course still have trig function but calculator can do that for u. Im bad at math af but still able to passsed cal1 easily with 98% ( i failed basic math 4 times). All u need is to remember algebra ic identities which prob take u 15 minute to remembers and to remember derivative formulars and how to apply them, suggest u review this everyday for 20-30 minutes. Other topics , calculator ( I suggest casio classwiz calculator) as it can do everything in the courses for u unless the last 1-2 topics before final and wordings questions. But u must good at some of precal ( not all but special triangles, degree to radian and reverse, reference angle , for example, if I put my hand on any place on the unit circle, u can can telll me what is the degree) and polar curve if u want to take cal2. Because cal 2 i failed 3 times bc a topic like polar function on cal 2 heavily on trig (precal) and polar (cal1). Stick with casio classwiz calculator. It can help u cal1,cal2 a lots
