I just bought the Knewton course. My OCD is acting up again so please bear with me.

I can’t decide which schedule to take, the 2 times a week classes or the once a week classes. I’m also thinking of just creating my own schedule and watch the archived classes. IIRC, the 2 times a week session is about 1 ½ months long, while the once a week session is about 3 ½ months long.
I’ve been preparing for the last 2 ½ months already. For 2 ½ months I’ve read pretty good books like Sackmann’s Total Gmat Math, Powerscore’s CR bible and
MGmat’s SC bible. These are solid books. I probably just need to read them again or at least review them.
Despite my preparation however, I scored very low in my Knewton diagnostic exam. (Q and V are both low, too embarrassed to mention right now

) I’m worried about regressing if I go with the once a week classes. I’ve read so much about the “law of diminishing returns” if I take my review beyond 3-4 months (something like that) or worse suffer burn out. On the other hand I might get information overload if I go with the 2 times a week classes. Has anyone tried either of the schedules I mentioned? How did you find them? Was it too hectic, too long or what have you? How about creating your own schedule and watching the archived classes? Has anyone tried this? Sorry for being too anal about it.

I just can’t believe that I got a very low score in my Knewton diagnostic exam, since almost everybody here seems to find the questions easy or at least not particularly difficult. Well, I did find the question not particularly difficult also. In fact I finished about 25 minutes early in the verbal section and 5 minutes early in the quant section. I’m just surprised with my very low score. I tried to justify it by finding some excuses such as my lack of sleep (5 hrs.) and my carelessness. But excuses are just that, the real gmat won’t care.
Whew. It feels good to get it off my chest. At any rate thanks for reading my whinings.

I just want to maximize my preparation without going overboard or regressing. My target gmat score is still 700 plus. Anyway, hopefully all of us get our target gmat scores. TIA
P.S. Just wondering, did anyone of you get the bonus MBA mini-course? My Knewton course doesn't seem to include it. Thanks.
