Becker FAR SEs Increasing in Difficulty?

Reviewing for FAR, and I take it tomorrow. I just finished my last SE and I'm a little concerned because I've been doing worse over time.

SE1: 80, SE2: 79, SEFR: 77

I understand these scores are pretty good, but my concern is my MCQ scores were consistently going down, and the TBSs were pulling up the score. Did anyone else have a similar experience? I especially feel like SEFR was the hardest when it came to the MCQs.
