yeah that's what i do too, i consider 25-30 sec. the fastest i can do it if i find the course right away, and longer if i have to dig for it. it just sounds like you're either finding the exact term you enter the first time you search or submitting it as not available. many of these schools require quite a bit of digging, especially the ones that have multiple engineering/computer science departments. just sounds too fast to be thorough.
