Given this information, in order to use his 4 hours of study time to get the best exam score possible, how many hours should he have spent working on problems, and how many should he have spent reading?

1 hour working on problems, 3 hours reading

2 hours working on problems, 2 hours reading

3 hours working on problems, 1 hour reading

4 hours working on problems, 0 hours reading

3 hours working on problems, 1 hour reading.

Explanation:

For any students involved in examination or any sort of things then, reading efficiently is the best way to achieve the highest score. If you have all total of 4 hours for preparing the exam then, the most time must be allocated for solving problems. For the time of solving 30 questions, it will be equivalent to the time spent for reading for 1 hour. So the best time allocation would be reading 1 hour then spending left 3 hours solving the questions related to the read chapters.
