KAPLAN vs. ADA vs. REAL OAT

So I take my OAT exam in 4 days and really nervous about it! I have been studying for about 3 months and I have taken 3!practice exams, 2 Kaplan exams and the ADA free practice OAT. I noticed a big fluctuation in my scores and wanted to know if I am going to be okay taking the exam. My scores are as followed:

BIO/CHEM/ O CHEM/PHYSICS/RC/QR/AA/TS

KAP 1: 330/250/260/250/320/300/290/280
KAP 2: 340/310/300/270/280/330/300/300
ADA : 390/340/340/360/ - / 370/ - / 370

I took the Kaplan exams...
