This also reminded me of some summer classes. Maybe one month, 5 days/week?

Some of the things that best remember from undergrad were learned over the summer.

I still don't know whether it was the short/intensive set up of the courses that improved learning, or if it was the fact that I was only willing to do summer courses in topics I knew I'd do well in. Either way, it's my best memory of school.

I always took advantage of summer quarter as an undergrad. It was a better experience though course selection wasn’t great (especially for CS).
