Akim,
This is a great start! In fact, better than my own first test exam when I was studying.
What I did was, after each practice exam, was to go thru each question I got wrong and understand WHY I got it wrong. I also went thru questions where I was primarily guessing at the answer (I kept track of the question numbers as I took the exam - I just jotted the question number on a piece of paper).
I also categorized the questions where I got the answer wrong, just to see if there was any trend regarding the mistakes was making. This helped me tremendously, because I found that many of my mistakes were related to my taking the test "too fast" and not reading questions carefully. I forced myself to slow down and think and that was a big help for me.
Congrats on getting off to such a good beginning.
Best of luck!
Tracy
