Hints for Logic Puzzles:

First fill in the obvious answers. Use a checkmark to identify the right answers, and an X to identify answers that cannot be right.

For each checkmark, put an X in each of the other possibilities that turned out to be wrong. For example, in the women leaders puzzle, if you find out that a particular person has the Computer Science degree, then she doesn't have any of the other degree choices - put X's for each of those for her. And, no one else has that degree - so put X's for each other person for the Computer Science degree. By process of elimination, you will eventually discover all the right answers. You might need to make a few passes through the hints, though - keep trying!
