My husband got this book from Amazon - '4 Practice Tests for Cogat'. It was only $26 and has tons of content for the Grade 2 Cogat testing in the format of the test. We have seen a bunch of books and this one is good. I recommend it. My daughter looks forward to working on it every morning.
Anyone knows if there are similar books for OLSAT?
The publisher of the OLSAT, Pearson, apparently publishes
OLSAT practice tests.
However, during checkout this warning appears: "Your qualifications should be on file with us before you complete your order or there may be a delay." This is probably a general warning based on Pearson selling a lot of psychologist-only materials, but you might want to call them to see if parents are also intended to buy those OLSAT prep materials. I don't know why they wouldn't be; practice is practice, and Pearson offers a lot of practice test bundles for the OLSAT, more than I'd expect just to familiarize a student with the format of the test.
If it appears that the publisher thinks practicing privately for the OLSAT is okay, here are a couple of additional searches that might help:
Amazon Google
