Actual Enhanced ACT Tests v. Official ACT Practice Tests

I'm studying for the July ACT. I've taken official ACT practice tests (enhanced) and the June 2026 test that actually was administered. I've done much better on the official ACT practice tests than when practicing with the official test (e.g., 36 on reading on official practice tests and 26 on the June 2026 test). Has anyone had a similar experience?
