Question about 70-294 and 70-298

Heres the thing I belong to a certification school currently and my term is running out. I will have to pay for the last two courses: 70-294 and 70-298. Question is will I be able to learn these two courses on my own?
I failed 70-291 and decided to move on. Currently I have passsed: 70-290, 70-270, 70-284. I will be jumping back to 291 after I complete 293. A few more weeks and I should be done.
Failing 291 kind of lost my motivation but I got it back.

Good luck!
P.S. A lot of people stumble on 291, so you shouldn't let that discourage you.
I have lab machines and Ghost at home so I might as well take advantage. Also have Server 2003 Enterprise. Is that sufficient for 294 and 298?
