/sci/ - Science & Math

Ok, so i suck at math, i didnt do shit through school but now i want to learn math, so where is the best place to start/ how to progress, i am thinking algebra but i dont know what good books ect are to learn.

Does anyone have any old tests from their calc II or calculus class over series? I need something to review, but I don't have a book for problems. Basically just problems where you have to find out which test to do and things of that sort (ratio test, direct comparison test, alternating series, ect,)

I know it's sort of a long stretch, but it would be very much appreciated. Any sort of advice would also be kind and well received.

What does /sci/ do when it can't solve a problem on a math test?

I usually just put the original equation over zero and circle it.

question!
got a class in which we are to design a trebuchet. we will simulate there performance. we also get to ignore friction on the machine its self.... what does /sci/ think about a floating arm design as being the most efficient way to do this?
