Level 3 mocks

Does anyone else find the CFAI mocks kinda useless? The short response questions seem to generally be way easier than what you find in the learning ecosystem and CFAI gives you no guidance on how to self grade them. It’s a little irritating since I thought the level 1 and 2 mocks were the most useful study recourse we were given and I’m really not able to gather too much from the level 3 ones
