I averaged mid 80s in radar. I went into radar after I literally tanked non radar. I averaged a 49. It just didn’t click with me. I came in with 25.74 points. Never give up. My first run i got a 100. I was shocked to be honest but didn’t let it get to my head don’t be so confident that you blow every other run. Second run got a 89. Third a 64. I came into radar 2nd to last in my class and finished third. Radar just made sense for me. As Nl1 said, there’s nothing you can’t do. Just breathe, talk confidently, show that you’re in control. It’s just another day running problems. Also if something changes with a aircraft do a double take on it, often they change it for a reason and it’s to bite you in the ass. Good luck.
