The most difficult part in the midterm was all the proving parts in few questions. The questions which asked me to explain or define were very hard to me. This was because I did not practice any problems about proving and defining. I had solved many questions about taking integration, integration by substitution, integration by parts, and finding volumes. However, it was little bit hard to practice prving things. Also, I spent too much time to write the poem to earn only one mark more. I had to spend more time on solving questions. I made few mistakes because I could not manage time wisely, so I was not cool enough to solve hard questions.
