I can only speak from experience, My dat test had 1 lab question, but it was answerable by just studying Kaplan blue book organic lab chapter. It was a very basic question.
Let me tell you something, orgo lab is a PAIN in the ass. I mean I loved orgo class, but the lab was just unenjoyable. In order to get the right grades, your products had to be above 85-90% pure. Out of like 30 students in the lab, I think the best one was like 79% pure and that was like "OMG HOW DID U GET IT THAT PURE"... cause most of us would be in the 40s lol..... Disgusting time, I hated every minute of it.... If they wouldn't have curved it, I woulda ended up with like a 2.5
Orgo was the easiest of DAT science questions for me. Studying the Kaplan book helped a lot as a refresher course but not necessary to have completed lab section. Try this web site: http://www.coursesaver.com/vbtube.php?do=list
Good ol' Chad. I didn't know about these videos. I see they've recently gone to subscription but the older o-chems are still available. I'd consider a subscription even. They'd make for great review before some sort of big test. Chad can pack an auditorium for hours with his reviews.
(I have no relation to Chad. I've just been to his reviews and they're extremely helpful.)
