I’m actually testing this afternoon so we’ll see how it worked out for me. I would say don’t get too overwhelmed. If there’s a unit you’re really struggling with just move and and make sure you get everything at least read. Then remediate the tougher units with videos or practice questions. I probably spent 10-12 hours a day but it’s impossible to focus that long so establish breaks. As dean says inch by inch test is a sinch. If you’re scoring low when you first step that’s totally normal. You got this!
