I saw this article a few days ago discussing one person’s opinion and experiences of why the number of engineering graduates is dropping in the U.S.

While I never even thought about dropping out of engineering for another major, I defintely experienced everything within the article, including a 58% Physics II grade that became a B! I also experienced a well known phenomenon at Alabama of taking certain classes during the summer semester so as to pass with a decent grade and not significantly impact your GPA – I attended 1 summer semester for a few such classes between my junior and senior year.
