Mine wasn't embellished. It did suck however. It's possible if the classes are staggered. ie you don't have all the classes at once. It also depends on how much time you need for studying outside of class and the difficulty of the course.
Just to lay out how this is possible, this is my course list for the summer between my junior and senior year, I don't remember the staggering exactly but something like this. Psych courses were all reading and writing intensive. Comp was a joke. Micro was a challenge.
BIOL 4501 General Microbiol 4.00 (in person 6 weeks, June session, all morning, lecture and lab)
COMP 3150 Adv Writ:Science 3.00 (indep. study 12 weeks across summer starting in June)
PSY 3081 History, Systems 3.00 (June session, online)
PSY 3112 Psychology of Religion 3.00 (July, online)
PSY 3445 Transpersonal Psy 3.00 (July, online)
PSY 3611 Learning and Behavior 4.00 (July, in person?)
PSY 5098 Psy Trans and Spirit Journey 3.00 (in person all day 7 days, May session)
TERM GPA : 3.942 TERM TOTALS : 23.00
So roughly 10 credits at any given time. Plus a flexible job that's non 9-5 and yes it works.
