Failed MEC by 3 points — what should I change?

Just got my score back. So close it hurts.

I felt okay going in but clearly there were gaps. Looking back at my prep, I spent a lot of time on "MEC" but I think I underestimated how deep they go on MEC exam.

The weird thing is I scored fine on the concept questions but tanked on the application ones. Like I understood the theory but when it came to scenario-based questions I kept second-guessing myself.

For anyone who's failed and then passed — what changed? Did you switch study materials? More practice tests? Different time of day?

Also curious whether the MEC score report tells you which sections you were weak in. Mine just shows an overall score and I have no idea where exactly I lost points.
