How do you find the Mid-term Examination in Computer Subjects?

I find it a little difficult. Our examination in CO112 is written exam and interview. In interview, out of 12 questions, I only got 9 correct answers. I did not answer some of the question because of “mental block”. We only have 15 minutes to answer the question. On written exam, I'm sure I got a good score. Our teacher is strict. He always walks around. I think no one attempts to cheat.

Our examination in CO113 is also written examination (multiple choice). Even if I review my notes, I did not answer some of the questions. Some of the question is not written on my notes. I thought the question involves the history of Arpanet.

But I find it easier than the examination on CO112.
