Yes. Too much longer and you might get burnt out and start to forget stuff. Study smart, efficiently and do lots of problems. If you need to review watch Chad's, but seriously the best thing to do is problems. DAT Bootcamp and Destroyer are really good. I had several questions today on the DAT in Bio and GC that were exactly the same as Destroyer. Go over problems more than once if you can so you make sure you understand them. You should be able to get through the 10 test version of CDP in 6 weeks no problem. Good luck!
