Just curious, I havent started grad school yet. But I know in my undergrad days, and studying for the PGRE I love solutions manuals.
Do many authors write solutions manuals for grad level classes
You might have luck in some of the more general grad level classes. However, there are two issues that could block that even so. Some specialized classes I've had didn't have one singular book really, if anything it was a collection of pieces here and there from references. Secondly, weather or not there is a book doesn't mean the problem sets will come from them. I'd say, at least for me as I can't speak for others, a lot of the problem sets my profs have assembled are from who knows where, probably their own knowledge, but definitely not a book I know. So keep in mind you may not even have traditional problems from a book..... As for.....
or should I prepare to ask the profs for alot of help with problem sets.
Thanks for the good laugh.... Not that they're not helpful, but in general don't expect a lot of anything except long days and nights.
