Need help on subnetting practice questions and RRAS setup.

hi guys:
I am trying to prepare for the 291 exam. I have at least 2 topics that I don't feel comfortable with. First is the subnetting. I learn and know how to calculate this thing long time ago, but have to take time. Although I always get the answer right, but i can't do it off the brain so fast. I dont' wanna get stuck during the exam. So I am trying to get some practice questions to help...boosting my brain CPU.
Second major topic is the RRAS. Honestly, I have never done ANY routing in windows. NAT, router, dial-up server, RADIUS, VPN......and so on. I already have a Pentium III machine with 3 NICS and 1 Modem to play with. However, I still couldn't be able to do many much configuations. I need more help on this topic. I wanna get some good sites that show the config in more details. I would also prefer step by step.
Besides, other topics are still fine that I should be able to get ready for the exam.
My reading is almost done. Its still march now. I am trying to take my exam in May and hope to get the MCSA done before my 29th birthday.
I am getting old....sigh....
thanks

there's a link called 'view/print practice problems.
Also, don't forget WSUS for the 70-291. From reading the posts here, it seems quite a few people neglect to review/study this subject at all.
