CAPA is worth next to no marks, but not attempting to complete each weeks set of questions would be a big mistake when it comes time for midterms and finals. It may seem pointless due to each only being worth like 0.2 percent or something small like that, but those questions are extremely helpful in gaining an understanding of the material and types of problems you may encounter on your midterms.

once you register your iclicker, do you have to re-register your iclicker for the next year ???

No, but you can if you want just to be safe. It takes like 2 minutes to register it.

Actually, you probably do have to re-register it (although I've never re-registered my iClicker myself and didn't have any problems) but they might have changed it for whatever reason:

NOTE: If you registered your i>clicker in Spring or Summer 2011, you will need to register again for Fall 2011. Your registration is valid through the end of this term.
