Just finished my prelims and midterms exams on Calculus 2 and Material Science and Engineering.

There were questions on Material Science and Engineering which I didn't see in the reference textbook, could be a side note from the lecturer.

In the differential calculus class last year we were allowed to use our scientific calculators but the exams included super difficult rational equations involved in the differential equations. In the integral calculus exam today, I took the special exam at the faculty office and I was not allowed to use my scientific calculator. I don't see anything hard on the equations except for the tricky involvement of trigonometric functions. Maybe the lack of hardness was due to the fact that it is already isolated on the integral constant.
