How to study

Here is an old algorithm for studying for tests:
For each topic on the exam, find problems on them and do them.
 If you can solve them on your own, move on.
 Else if you are stuck, look at the solution and figure out if you
 are missing a trick or if you do not understand the concepts.
   If the problem is that you are stuck on some random trick,
     just learn the trick.
       Stare at the solutions, ask Piazza, your TA, etc.
   Questions you should ask at this stage:
     What is the problem asking me to do?
     How was I suppose to follow the instructions
       to solve the problem?
     What part of the problem do I not understand?
     What is the fastest way to clear up that misunderstanding?
  Then if you think you are still stuck conceptually, review
  and learn the concept, however you learn best.

  Suggestions for picking up concepts quickly (~1-2 hours):
    Discussion notes typically have a very concise recap of the
      thing they are going over.
    There are guides for particularly tricky things on the wiki,
      like Hanoi, powerset, etc.
      Find them and go over them.
    Ask a TA: "what is the best way to learn X?"
    If these do not work and you are still shaky after an hour
    or two, it might be worth watching a lecture or reading
    the notes. Be sure to try out some more problems as you're learning!
