When did everyone start revising for SBM?

I've gone through all the content for SBM but I've been spending my time focusing on CR since everyone says that's harder so I just wanted to check when people actually started going through the QB for SBM? I know there's still plenty of time but I don't want to fully neglect it so I wanted to know what worked for others.

Thanks in advance for your help.
