"Great video"
The man has a very simple, memorable way of explaining things which is memorable and helpful. However, I didn't give the last star just because he looks like he's miserable. He could attempt to look like he's a little less miserable, although I've seen much worse.

"PROBABLY NOT FOR LD/ADD KIDS!"
[Full Disclosure: I have some experience teaching math, physics, and technology at the high school level. I have also taught film and video.]

I ordered this for my son who is in college.

Clearly this video series is a home made product, which is fine, but given what even an amateur can do on a Mac with iMovie and iDVD, the production values are, to be kind, non-existent. Talking head ad nauseam.

Also, these videos are obviously "lifted" from within the series, with no attempt to make them a stand-alone product. These is made evident by an opening line making reference to previous material.

I was disturbed to notice some "reviews" posted for some of the titles in this series which appeared as if they were placed by shills, if not by the producer himself. This almost caused me to select something else. Honesty counts.

Overall, the material covered is covered acceptably, provided you can stare at a white board and watch a talking head while remaining receptive to information. For many students who are having trouble in the classroom, there is a need to support other learning modalities. Unfortunately, this video simply replicates the traditional classroom experience, but without the option of asking questions. And, as others have pointed out, these titles are not comprehensive.

One last complaint. When the package arrived, I was upset to discover that the discs were floating around loose in the case, and they had taken a beating equivalent to giving them to my dog for use as a chew toy.

I haven't ruled out ordering anything else in this series, but I am going to order something from a competitor for comparison before I return to this series.

"An okay basic review"
Id recommend this DVD for someone who has taken pre-cal and needs a little brush up on some basics. I didn't find this DVD to be very in-depth at all, and not suited for what I was looking for. I tried to use this DVD in conjuction with my class and it really didn't cut it. I would recommend the Teaching Company's High School Algebra II for those about to take or who are taking pre-cal.

"The best teacher around!"
The Trigonometry and pre-calculus tutor was very helpful. It doesn't cover advanced Trigonometry, but teaches you the basics with a lot of examples.
The tutor, Jason Gibson, basically teaches you every derivation of the identities. You can use this DVD for basic Trig preparation and get an advanced book, which is probably available in your library.

And it also teaches Exponential and Logarithmic functiions, and Imaginary numbers.

I bought the USED DVD, which was very good. I suggest you guys buy the used version at a cheaper price.

"Dry, but helpful"
I used this while in college. It did help me get an A in Pre-cal. It was a little dry. The lesons were strait foward. No CGI or graphix. I did find it useful, but maybe younger students might find it a little boring.
