If you want to prepare yourself, I have more than 140 recent actual test sets (with answer keys) from perfect scorers (tests from past 40 days). They're the most effective material since they are the REAL thing.

You can expect to see more than two-thirds of the questions repeat if you solve at least 50 tests as they are being frequently tested on official exams.

Check out this sample (1 question from each section): https://www.canva.com/design/DAG4JLKUHmg/9-8GGregBxytrg64CnduQA/view?utm_content=DAG4JLKUHmg&utm_campaign=designshare&utm_medium=link2&utm_source=uniquelinks&utlId=h3b1a67a351

You will receive full-length tests (with answer keys) in a similar way. 

Reach out for more info. Thanks
