cs 107 is NOT supposed to be very difficult but the way Dale Reed teaches it, he makes it EXTREMELY harder than anyone else who tries to teach it. for proof, assuming he hasn't changed anything, he has everyone take in-lab portions of exams that are worth half of test grades. even worse is that those in-lab portions are pass/fail. he is a good teacher and a good man, just his teaching methods are very very very flawed. i can say this because i have taken his cs 102 class in the past, which is computer science equivalent. in my opinion, if you do choose to take 107 with Dale Reed, do two things: one, find a mad programmer so he/she can help you on all 5 programs AND do well on the in-lab portions.
