## Test 1

Test 1, worth 15% of your final grade, will take place in the usual D160 lecture venue at 10:00 on Tuesday 15 October.

You can find a sample here. I will give ye a copy of this next week.

Test 1 will cover the contents of Chapter 1 and the sample will give an idea of the layout and length of the test.

The following *types* of questions are examinable:

- P.22, Q. 1, 3, 4, 6-7, 9, 13-14
- P.28, Q. 1-4
- P.32, Q. 2
- P. 37, Q.1-3
