Yes. I don't know that I would spread it out over 6 weeks though...I would think one would start forgetting stuff. I crammed it into just over 2 weeks and had one week left to work on weak areas and memorize piddly stuff, all while doing at least 48 (random, timed) UW questions a day (usually 2 blocks a day, one in the morning and one at night). Doing timed, random questions, in my opinion, is just as important as anything else.
I did this and totally dominated my boards. (One small caveat though...for 2 weeks prior to starting DIT I sat through live Kaplan lectures which our school provides to us [also doing UW quesitons], and I worked hard and did very well my first 2 years of med school, so there was very little re-learning and more reviewing. But I still completely stand by DIT.)
