Same I want to confidently score a little higher pre-BR but progress is really slow...
I started using a watch after I saw Dean's post. It has helped me with skipping questions. If it takes more than 1.5 min I skip it and come back to it.

Hey, this is my fault. It's from a batch of website improvements I pushed out last night. These website improvements normally can lead to formatting/color/layout issues for some students for a few hours.
Ya, you're fine! You're utilizing the PTs well. (Even if you use it all up, it's not the end of the world. You can still improve your score and progress further.)
