By all means, take the honors series. I was not an honors student, but I enrolled in 6ah,bh,ch no problem. I did really well too (A, A+,A+), and that isn't because I'm a genius. The honors series has a much more generous curve, which buts average between a B and B+ instead of the usual C+ and B- of most of UCLA. The classes are smaller, and the material is centered around biophysics. You use a course reader instead of the Serway/Jewett (spelling?) book. The labs are also a little different. Overall, the honors series is much better. You have to take ah in fall, bh in winter, and ch in spring though. That is the only time they're offered. Good luck!
