I just logged on and everything is locked. Drills are locked, preptests are locked. Everything. Is there a bug?

Hello everyone. Since my diagnostic, until now I have gone up about 13 points but I am still yet to reach my goal of 165. I have taken countless PTs and have been drilling almost every day for the past 6 months. My biggest problem is managing my time. In the LR sections, I always finished with 5 unanswered questions. On the RC, I only get to finish 3 passages. I know some say that there is only so much more you can improve after having studied for a long time, but I refuse to believe that I have plateaued. There has to be a way.

Does anyone have suggestions for how to finish on time with accuracy?
