What's the "easiest" selective course you've done?

Looking at 30+ selectives offered throughout the term.
I know things will get even more complex once term 3 + 4 + 5 hits
After talking to advisor, I was told that all students participate in at least 1 selective during their stay here on campus

1. When do students usually take the selective? Which term?

2. What is "easiest" or less stressful selective offered?

thanks!
