Two parts of the exam A and B, all the similar questions in two files names of Review Questions, need it for 36 hours.

Here is what professor says:  

I have put the review problems for Final Exams part A and part B right next to the actual exams. Please note that there are many solutions to the problems at the end of the reviews.

I have tried to double check the problem numbers with the answer numbers, so there shouldn't be any errors. I also gave answers to similar problems, so if things appear to be improperly numbered, you can figure things out yourself since you can match up the answer solutions to the problem contents.
