Scored 5 ATs on my 1st try

Overall my preparation time was about 200 hours.
Managed to take fully the only 4 sim tests and the score was relatively stable 71-73.5 -73.5- 75.5.
All the four tests were during the last 10 days before the actual exam.

At the end didn't have spare time to review any flagged questions. Both during all the mock exam and the actual test. Indeed, my performance was declining drastically during the exam, probably due to fact i'm not native in English. Interestingly, during the mock exams the performance was much more stable, but i didn't have spare time a all as well

Can't say the first questions during actual exam were more difficult, fist impression was they were much easier than average I had during mock tests.
Overall I find mock exams questions more difficult
Can highly recommend Exam Simulator. Didn't try other sources much - can't compare.
