Ya, BR whenever possible; helps you see what is a timing issue and what is more of a fundamental misunderstanding of the material. GL!

PT's are not really meant to develop/lessen your confidence. It is more so a tool to observe your strengths and weaknesses to adjust your studying plans. Just check the curve for that PT and add points based on the experimental if it is important you see the other score; but, treat a PT as a PRACTICE test. There's no benefit in raising/lowering your score as it is not an option on test day. When I learned this, it really helped me study better.
