WHY OAT DESTROYER IS CHALLENGING AND WHY THAT IS A GOOD THING
Students sometimes contact us and say they are getting many OAT Destroyer problems wrong.
Our response is always the same: Good.
It is far better to discover your weaknesses while studying than on test day. The purpose of challenging practice problems is to reveal gaps in understanding early so they can be corrected before the exam. Each missed question becomes an opportunity to review the concept, learn from the explanation, and strengthen your understanding.
This is why the OAT Destroyer is intentionally challenging. The goal is not to make practice easy. The goal is to help students identify weaknesses early and turn them into strengths before the day of the OAT.
