Impressive! How many credits did a "normal" class (like linear algebra or calculus I) have? Or how many classes did he have to take to get 40 credits in one semester? The exam taking phase must have been hell :P The best I once did was only 48 credits (with the baseline for full-time study being 30 per semester, "normal" class giving 6 credits, european university so only a 3 year bachelors degree) and I was very tired after that semester :D
