I also have been testing the same and have a goal score of 160 too with high BR. Honestly Ive been trying to drill questions types that I notice were constantly appearing as wrong in my BR. I also believe I crack under pressure. I saw something on TikTok that if you put all you put all your wrong answers in chat and ask what the pattern mistakes you keep making and apply its was helpful so I plan to do that on my next Pt test. Hope this helps you and I would also love to hear anyone else's tips!

Me please
