Great content – Need an advice

The course structure is great. I really like how the tests are divided in different types and categories. I got around 62% in all 4 timed exams for the first attempt and went through incorrect answers for a week and also read cheat sheets and other docs from TD. Now i’m getting around 85% in the timed tests. Can someone please tell if this % is good to go for the real exam? I want some guidance from people who already attempted the exam. How is the real exam difficulty level when compared to the questions here? thanks in advance.
