Proper way to grade Boston '21 AM session?

What is the proper way to self grade the AM session of the Boston CFA Society mock? Kaplan, for example is pretty specific when they say 1 point for circling correct answer and 2 points for each correct explanation or something to that effect.

I can’t find similar guidelines for the CFAI AM session so any help would be appreciated. Thanks

Do you have access to a random number generator?

I assume you’re joking…
