We've linked almost exclusively to online practice exams. You take the real exam on a computer, so prepping on a computer makes good sense. But for some, being able to grip a practice exam, scribble on it, and, if necessary, tear it, stomp on it, and/or throw it across the room are deeply desired qualities.
Great for all of these reasons: SWTP's newly published pair of practice tests, now available on Amazon and elsewhere. The exams are the same as SWTP's ASWB Exams #1 & #2. If you already have those, move on. If you don't and order the books, you get access to the online versions of those exam as part of your purchase. Do that and you're studying every which way.
However you're prepping, do some practice tests. They help. Enjoy!
UPDATE: Book #3 now also available. Buy all three at a discount here.
