It's a trivial task and certainly does not require attending an early morning class. In fact, most engineering does not require the degree. Almost everything in the field is self-learnable in a short period. The reason the students are in the class at 0750 is not to learn how to do this, since it is trivial and almost everyone I know could do it by the 10th standard two years prior to college. It's because no matter what you know, the credential is bestowed by 4 year attendance of 0750 classes, and the credential is what the university provides.
