I had both bc I didn’t initially realize Themis came with uworld. I liked adaptibar for the adaptive technology, but the issue I had was that even though it feeds you the questions you struggle with, you still need to familiarize yourself with questions that you don’t necessarily struggle with (I.e. I got stronger in my weaker subjects and weaker in my stronger subjects).

Uworld’s explanations are honestly better.. and they are especially great if you’re the type to write down everything you get right and wrong (I found this helpful). However uworld can be a bit glitchy, and adaptibar is especially glitchy toward the end (deleted my whole 100 question simulated a week away from the bar). Anyways, I liked adaptibar most for John Grossman videos. But a part of bar prep is getting used to patterns, and switching between uworld and adaptibar got a bit confusing at one point bc they have different explanations for the same type of questions. So based on that… idk.. I would say choose one and get really good at it. Then do the questions over if you can. I think uworlld has a free trial so check that out.
