Hey, I've been working through most of the EK 1001 Chem problems and I agree with mterp45. It's taken me almost a month (partly because I am on break and more lazy and partly because I was especially weak at gen chem). Like mentioned above, I would follow what EK recommends, do every few problems and if you are getting a lot wrong go back and redo more of them (this is what I will do for the rest of physics, orgo, and bio). Also as my spring semester is going to start next week, I won't possibly have enough time to do all of the problems anyway!
good luck!
