First, congratulations on graduating from the LPN program. That must have been a great accomplishment for you. Secondly, if you enter "NCLEX DISCUSSION FORUM", at the top of the page, there is a sticky called "REVISED FIRST TIP OF SUZANNE'S PLAN".
Suzanne is a moderator here for this website and she has a great review for RN/LPN's. She uses only the Saunder's Book, and since you have it, that's a great start for you. It is your choice however, if you need a comprehensive review or not.
Finally, if you just don't know where to start, I would first, read the beginning of the Saunder's Book. I know in the beginning of the book, they explain what the NCLEX test is, the plan, and they do cover strategies. That will at least give you a start. Then, if you decide to continue and use Suzanne's plan, just follow her first tip. I would put a link to it in this message, but I don't know how.
Hope that helps,
