not alone. You can go to some supply houses and take them online there (w/ a proxy in the room) if you could take it at home it would defeat the purpose of having a test since you would have nobody making sure you didn't cheat.
This is where I got mine from. They practically give you the answers, no joking. Search my postings, I recently wrote a few thimgs about it. Test took me 20 minutes to complete & I passed all the sections & core.
