Biting nails and twiddling my thumbs

Last class, we had a test dealt with two chapters, seven and eight. It was excruciating for that I had second thoughts for each question, which lend me to have my time consumed in one question to another. I simply do not want to take another test but then again, it is for my grade and better understanding of paragraphs and essays. I do hope to be well-prepared in the upcoming tests for that I cannot take another awful grade such as my previous test score.
