Topics and sample problems for Math 017 Final Exam
(long version)
Below there are 59 categories:
9 “arithmetic” categories
13 “easy algebra” categories
24 “basic algebra” categories
9 “difficult algebra” categories
4 “very difficult algebra” categories
Each version of the exam will be created as follows:
First, 45 categories will be selected: All 9 arithmetic categories will be included. From the
algebraic categories, 8 categories will be selected at random from 13 “easy” categories, all
24“basic algebra” categories will be represented, 3 out of the 9 “difficult” categories, and 1
from the“very difficult” category. After this process, we will have 45 categories. One question
out of each such category will be selected at random. Thus, the test will consist of 45 questions.
