i'll say as i did in my post in my thread. it really is a personal decision. $150 is a lot of money, but since i wasn't taking a course i figured i would try it out. read everything about it, especially from the people who don't like it because thats who you find the most information about it.
i didn't like the bio section so much, i feel like it missed the focus of my dat. but in its defense, there is a ton of material in bio to ask so it must be hard. there are a couple of problems in the bio section that they said "know this" and im glad i paid attention because some of those things were on my exam.
chem, orgo, and qr seemed to give a lot of help though.
and to dds4tehwin, do you think that he pays people to advertise for him? why would dr romano do that when he doesn't have to, it gets advertised enough on here by the results people get.
