ECE 302, Midterm #2
7:008:00pm Tue. Mar 28, PHYS 114,
1. Enter your name, student ID number, email address, and signature in the space
provided on this page,
NOW!
2. This is a closed book exam.
3. This exam contains 6 questions and is worth 100 points + 15 bonus points. You
have one hour to complete it. So basically, you only need to answer
≈
5 questions
correctly to get full grade. I will suggest not spending too much time on a single
question, and work on those you know how to solve.
4. The subquestions of a given question are listed from the easiest to the hardest.
The best strategy may be to finish only the subquestions you know exactly how to
solve.
5. There are a total of 13 pages in the exam booklet. Use the back of each page for
rough work.
6. Neither calculators nor help sheets are allowed.
7.
Important!
There is
no
question
identical
to the exercises, and therefore trying
to duplicate those solutions from your memory will be given zero credit.
8. Read through all of the problems first, and consult with the TA during the first
15 minutes. After that, no questions should be asked unless under special circum
stances, which is at TA’s discretion.
You can also get a feel for how long each
question might take after browsing through the entire question set. Good luck!
