Is studying for the SAT enough for the PSAT? Is there anything specific I should focus on the PSAT? Are there any major differences?

I got a 730 on Aniko Reading and 790 on whiz.study Math. 1520 superscore, but whiz.study felt significantly easier than Aniko math sections. Is this normal?

So im practicing command of evidence questions using whiz and the answer key says its A which I got correct but then when I gave the question to chatgpt and I explained by reasoning it said C was still correct so I searched up the question on google and it says C is correct so im confused am I right or wrong A seems more correct because it directly supports it by saying to be able to understand the timelines and scales of the eruptions you have to be able to identify and match them and in A the first part of the sentence is the identify part and the last part is the timeline part

I just took the June SAT and my friend introduced me to this website. I checked through it and I got about 8-9 answers wrong and just might score 1430-1450. Anyone?
