My genius plan for science test

This was what happened yesterday: When I was studying the study guide since I reviewed the textbook twice already. I felt something weird in my stomach. But I ignore it because I didn't really care about my stomach and I was listening to music with earplugs. However, after five minutes I had a stomachache. I tried to ignore it but I fail. I spent about ten minutes "fighting" with my stupid stomachache. However, I thought of a super x2 brilliant plan for my test. I got 85 or around on the last test. I remembered Mr.Liu said that she will drop the lowest grade in test, homework, or lab. I put my take-home exam as primary "mission". I ignore tomorrow's test because she can drop that final so I do not have to care about that test. I got so bad on my English test. However, Mr.Dhal said I improved a lot. I don't really think so... I think I still have some problems on words used in opinions A,B,C, or D.
