Another way to search for exercises is by basing your search on how you've used the exercises in the past.

For example, you can mark any exercise(s) as a "favorite", and then from your dashboard, you can list all your favorite exercises. (This is similar to the "bookmarking" feature that you may have used in browsing the Internet.)

Another possibility is for you to mark an exercise as "finished"; then from your dashboard, you can either list all of the exercises that you have not finished with, or all of the exercises that you've already explored. (Note that simply going to an exercise doesn't mark it as "finished". This is so that you can skim through an exercise as many times as you want. You decide when you've finished with an exercise!)

You can also list all the exercises for which you've written a note to yourself. But to really understand this capability, you need to examine the difference between notes and comments. (See the next exercise.)
