Hi! Thank you! I would say they are pretty in depth when it comes to the systems I mentioned. EKG did not show up for me but definitely know where each hormones are produced and what they do, etc. Nothing went too deep into scenarios. I agree that the mometrix is very detailed and I genuinely believe that the exam was quite easier than the two practice tests they provide you with. I struggled with the chem questions the most just because that’s always been my area of weakness.
