I think that this program will not help many students because it is hard to cover 4 classes in a 7 and 1/2 weeks, therefor students will take less classes which means more semesters and that takes us back to the same time as they would have taken if they had chosen the regular 15 weeks semester.
If I had to choose between the short classes and the normal ones, I would choose the normal ones because I am an old fashioned student who got used to the 15 weeks semester and besides the short semesters would be a stressful semester if some of my subjects were crammed into 7 and 1/2 weeks and would be hard to get a good grade in these subjects.
