Thank you for the kind comments, though it did not make me happy reading the comments above to hear about link rot setting in at the Learning Center. Aaaarrggh! (I've fixed most of it). One of the things the site tries to do is bring the rest of the web into focus for premedical students at a very fine grained topic level. In the learning center, you will see about 1200 topics (the outline nodes within the chapters) and roughly 2500 links associated with these to sites around the web. Although there is a button for visitors to push to notify me of a dead link, I haven't been seeking traffic, just working on the site, so there hasn't been anybody to let me know, so I'm glad to have gotten a chance to fix them before more people visit. Thanks!
On a related note, I am someone who has pretty much surfed the entire educational science resources on the web and I also know a great deal about preparing for the MCAT so I will share my opinion about which sites (along with WikiPremed of course!) are the best for science study for the MCAT, one for each discipline:
PHYSICS - HyperPhysics -
http://hyperphysics.phy-astr.gsu.edu/hbase/hph.html
CHEMISTRY - Bodner Group at Purdue -
http://chemed.chem.purdue.edu/genchem/topicreview/index.php
ORGANIC - Virtual Textbook of Organic Chemistry - William Rausch - Michigan State University -
http://www.cem.msu.edu/~reusch/VirtualText/intro1.htm
BIOLOGY - Kimball's Biology Pages -
http://biology-pages.info/
Using the web for study has advantages and disadvantages compared to printed materials, so think a bit about this before you dive in. With a printed resource, it is easy for your mind to grasp the beginning and the end of a topic. A book has a physical shape. A definite number of pages. A table of contents. However, with a website, the knowledge can have a way of seeming endless, with links peeling off over the horizon. It's really crucial to understand this difference, because one of the most crucial stages to reach in MCAT preparation is to be able to see the whole thing from the bird's eye view. This is when the thing clicks. My point is that if you use the web to study, you have to be careful to stay oriented within the learning goals of preparation and within the outline of the sciences. If you do that you can gain a great deal from the web.
A big advantage of using the sites above is that their authors are really excellent at explaining ideas in science. (In General Chemistry, I also want to mention the Chem1 Virtual Texbook by Stephen Lower -
http://www.chem1.com/acad/webtext/virtualtextbook.html, which isn't as well organized as the Bodner Group's site, but which has some great discussions).
The web can help you because while a great deal of MCAT preparatory material is uninspired, indifferent, and ill informed, even with the best materials, such as ExamKrackers and Kaplan, there are many topics where you might find a need to add depth to your conceptual understanding.
I hope the sites above help you in your studies! Good luck on the test!
