Princeton Review vs Real OAT

Hi everyone,
I’m a little over a week away from my OAT. I’m reading Princeton Reviews “Cracking the OAT” and it comes with 2 practice exams. The two practice exams seem very very easy in comparison to the Kaplan ones I’ve been taking. I was wondering if anyone has done these two practices and how do they compare to the real OAT? And how do the Kaplan practices compare to the real OAT?

Thanks in advance!
