I definitely pick and choose which ones I accept. If they have an online search for their catalog, I will give it a shot. If their catalog is in PDF format, I skip over it, because I don’t have time to be downloading a bunch of large PDFs. I end up choosing 2 or 3 universities and skipping all others. If you can do one a minute @ 30¢, you are in the $18 per hour neighborhood. I don’t work that fast, personally - but it is in the realm of possibility.
I googled the university name and the class name. In one I got a link to a list of departments with the name of the department head, but no links to any class names or professors.
For the instructor HITs, I just googled out "*school name here* class finder" and it took me to every search system for the school. I was able to do HITs within 45 sec. to a minute each. The only problematic school was Northwestern, so you have to play with the finder and use their site search.
Ok, who's got the end-all of tips for these instructor hits? I got my course strategy down, I just need to figure out the best way to do instructors.
If it hasn't been posted here is the schedule for kansas state university http://courses.k-state.edu/spring2013/schedule.html For hofstra https://hofstraonline.hofstra.edu/pls/HPRO/bwckschd.p_disp_dyn_sched
One hit got a pretty promising Google search. All the results wanted a log-in of some sort. One needed an email from that particular university. The University was not on his list. Not working at all.
I'm just going to stick with Oscar, available Crowdsource hits, and the occasional 20-50 cent surveys when I can find them. That seems to be my limit.
