Best resources for Science TEAS7

Really need some guidance on where to study the science portion of the teas exam.

I bought Nurse Cheung's book, but I'm seeing a ton of negative feedback.

Where can I actually practice the REAL questions that will be on this test, man? I have the ATI book questions as well. Do I simply look through that and study the topics that are in the questions or what? I feel so lost on this and I only have a month to study.

I would sincerely appreciate anything guidance.
