you are on the right track for sure.
keep this in mind:
UWSA1 is MUCH harder [IMO] than 2. For uwsa 1 I got 230, on uwsa 2, 265+
-Rx is a bad qbank: they take a concept/ an answer that they want, then toss in info that more often than not will contradict the answer or make absolutely 0 sense or just be plain wrong. People say "its good to solidify first aid", ok I get that, but the quality is lacking and will make you question if you know basic sciences lol
-Kaplan is good, I loved their physio section [tons of arrow questions, kind of like what you will see on your test]. the other stuff was too detailed orientated but I used it near the end when i needed fresh questions
-UW is the gold standard, just dont go too crazy with annotations. Either way, as long as you are learning from the qbanks you are golden. More so it shows you are grasping concepts so you are for sure on the right track. Do an NMBE and that will tell you where you are at.
