Has anyone tried thinkwell? I know there are ALOT of videos and about 10 minutes each but what i'd like to know is do you think its beneficial/helpful? Im not really in a time crunch/rush to take the DAT again so i have a few months to study, do you think utilizing thinkwell is a good source for bio? Last time i took the DAT i studied from Cliffs AP bio and i got a 19 on bio. I'm going to try to supplement my cliffs with thinkwell this time? I'm not sure though, any input?
