 * - To practice for the test download K-map software and install the software. Pick a K-map size (2 -> 4 variable) using the slider at the bottom of the window. Fill it the K-map with 1's and 0's (don't use *'s) and then work it yourself and press analyze to see the computer generated answer. See help for how to fill in k-maps using Truth Tables as well. Note that | is used instead of a bar to indicate a NOT.
