Sharanya,
You mentioned AWT. Are you working on the 1.2 or the 1.4 version of the exam? If you are working on the 1.4 version, then you don't have to worry about AWT.
In addition to the 1.2 version of his mock exam, Marcus also has a 1.4 version.
If you scored 80% on Marcus Green's exam, then
you should do well on the real exam.
Your score on the real exam is likely to be a lot higher than your score on my exams.
