What did taking 2x classes gave me?

What did taking the fourth and sixth semester's classes in one semester gave me? Did I benefit from that? The answer is: nothing, nothing good. Asides from immeasurable stress, burning busy work into my brain and an inflated GPA it gave me nothing at all. There are all kinds of "university pros" who do this but I think that for any sane person this should not be attempted. Being very smart won't increase your success and attempting this will damage your brain in an irredeemable way. It was attempted before and will be attempted later but I strongly advise against it. I still can not finish university earlier because of these stupid class dependencies and I don't feel that good after this. (Besides that, you will have the time of doing these classes in the respective semesters.) So my advice: DON'T!
