Document Summary
Solutions to term test 1 - october 6, 2015. Aids permitted: casio fx-991 or sharp el-520 calculator. General comments: the results on this test were very good. An average of 83. 8% is just like old times! The challenge is to maintain these good results on the next test: in the true or false questions, question 8, you should know by now that you can"t justify the truth of a statement by giving an example. You must give a general argument: many of you still don"t realize that it is not enough to plop down symbols, expressions, or equations. You must lead the reader through your solution; that"s what present complete solutions means. Breakdown of results: 933 students wrote this test. The marks ranged from 42. 5% to 100%, and the average was 83. 8%. Some statistics on grade distributions are in the table on the left, and a histogram of the marks (by decade) is on the right.
