A professor at Tulane, Prof. Gary Roberts, gave me the following advice: "And here's a faculty perspective: Students should not feel it is necessary to take any of the law school prep courses available or that they will be at a disadvantage if they don't, since we operate on the premise that students coming to law school do not have any prior training or experience in the field."
Tulane has a board just like this one, in which students, faculty, etc, can post messages just like this one especially for admitted students. I asked the same question and I got that response and this one from Admissions: "This question came up last year, too. I was able to identify three students in our entire student body who had attended this program. One student felt it was worthwhile, another thought that it wasn't as worthwhile as it should have been for the money, and another felt the first day or two was extremely valuable, but that the remainder of the program was not."
Hope it helps you out, I decided not to take the course but obtained the book "how to succed in law school" for free at my local library.
