Here is a list of some good problems to practice on. There are far too many to do, and some might be harder than others (and many are harder than I would ever ask on a test).

L'Hopital's Rule: 3.5: 1-33.
Indefinite integrals: 3.6: 12-24.
Riemann sums: 4.1: 11, 15, 19.
Definite integrals by computing area: 4.2: 2,4,7.
Properties of definite integrals: 4.2: 6,8-10,12-13,15
FTC: 4.3: 8-18.
Substitution: 4.4: 1-23.
Parts: 4.5: 1-5,7-11,13-14,17
