I doubt there's anything good out there in terms of tutorials or courses. That site you linked doesn't look even remotely close to being comprehensive. The review books (Princeton Review and REA) are okay for practice questions, but not so much for review.
Your best bet is reviewing material from your lectures. You should really devote a lot of time (more than a few months) to prepare. Maybe even more if its been a long time taking these courses. Here's a highly voted post from Math Stack Exchange:
REA books or Princeton review are not so useful.
Make sure that you do each and every problem from Stewart Calculus atleast twice, since its timed test, pace is also important factor.
Do Dummit upto field extensions, if you have time do Artin's Algebra too.
Rudin Real Analysis, Munkres Topology, Insel Linear Algebra are also must.
I suggest to go for Gamlin Complex Analysis, Brown's Complex Analysis is also sufficient but if you are good at Complex Analysis you can save time in the exam by simplifying integral using methods from Complex Analysis. (Do till Residues)
For the misc topics pick any Discrete Maths book and read them a day or two that's more than enough.
Learn some basic number theory from any introductory book.
Do all the 5 available practice tests, you should be able to finish of the tests little earlier because actual test will be harder than those practice tests.

I do personally think Rudin and Dummit/Foote are overkill but reviewing these two will also help with your graduate study.
