CS 1713 Introduction to Computer Science, Fall 2009 Exam 3 Comments

The exam average was 58.
Many of the grades were very low
Fewer than half of the class got more than 3 points (out of 20) on the insertion sort.
Less than half of the class recognized that problem 4a was just indexOf.
If you got below 60, you are not prepared to continue with this course.
Almost half of the class could not trace an insertion sort.

Grading: Since I told you that you could skip Problem 6 is you were running out of time.
I calculated your grade in two ways:
with problem 6 and without problem 6, and gave you the higher score.

1. For Strings, you need to use equals and compareTo.
2. More than half of the class could not do this!
3. Problems 3b and 3c are almost identical to the ones done at the beginning of class on Monday.
4. You need to know what the standard String methods do: length, charAt, indexOf, substring
5. This was supposed to be an easy problem.
6. Try to understand the logic of what you wrote.
7. There is never an arrow pointing toward a variable.

8. This should have been easy.
