Don't just do the feedback. When you get to the IR, you will look a real dummy when the examiner asks you about the airspace you are taking him into and you say "B isn't it."
You need to be flexable and learning answers won't give you that.
One thing that amazed me in the exam halls was those people who were out of a 2 hr exam in 15 mins. I couldn't read the paper in that time, never mind answer the questions and check it. They will make great pilots...not. It's the same as paying for a TR. Why does everyone have to have it the easy way and tomorrow. It just screws everyone else. Same as the exams....once the questions are leaked, they just get more abstract as the CAA get everyone back.
Just get on with the job and work.
