Step 2 CS- How to Study with study partner. Please help !

Hey guys. This might be a dumb question but I'm not sure how to approach studying with someone for CS.

Do you both read the cases from the First Aid BEFORE you practice? Or do you just meet and start timing each other? Do you read the topic from the CK book instead first and then start timing each other when you meet?

How is it done?

Any advice is valued thank you !
