I hope others more expert than I will offer you opinions too, but here are my thoughts @domainzd
If you have not told me your intended meaning, I had thought ExRap was intended for those leaving rap music (which in my old fashioned mind should be everyone!). It's short and pronounceable and I could see someone getting it as a brandable, in addition to your proposed use. Odds are it will not sell, but if it does I see something lowish $$$$. A not bad name at all really.
I am not clear on the intended audience for WoodVacation?
I like YourWebSchool, even though somewhat general. If you can find someone setting up an online program, could see something $$$ to very low $$$$ possibly.
Of course like almost any name, odds are against sales in any one year. Best of luck with them!
