Is the Mcgraw-Hill ACT prep book any use?

I picked up one from a library with 8 practice tests. Do you think that the materials there are less hard compared to the actual ACT? If so, I would like to keep note of it. If you can, please give me an estimate of it’s comparison to the actual test like, for example, 80% difficulty in comparison. If it makes any difference, it’s from 2010

Does it has relevant topics and so forth. I just need to be informed and conscious of everything while I prepare for the September test. Thank you :slight_smile:

I can tell you the actual test is going to be harder. However, don’t worry too much on that. Just do as much practices s you can. Keep in mind though, the act will be using its new version in the spring. Best of luck to you! :slight_smile:
