Don't stop no matter how hard the material is

Today I bummed the quiz getting a 3/10 on it but the mistakes were minor. Even though the mistakes were minor a bad grade is a bad grade. After class I worked on more problems that were similar to the problems on the quiz so I could better understand what I was doing. After working on all problems in about 3-4 hours I finally understood my mistakes and am ready for the test.
