I like the LearningExt so far. I did a 150 ques pretest and then it has lessons for everything - with questions after. Then it has a bunch of post tests for different topics and random. I like it. It has rationales and most of the tests give you rationales right away. So the ATI books have info, but won't give you the testing material. If you think you can stay focused online, I'd reccomend it. Things is - you can pay for the 3 weeks and if you like it and have more to do, you can extend by paying again. And it's just not that much money. I picked 5 weeks and should be through all I want by then. I am picking and choosing the review material based on how my tests are going. I also feel good about doing a review offered by the people who make NCLEX.
