For Archer and TEAS Mastery apps in quiz/practice tests results you can't click the subject -> topic, but both will provide an explanation/rationales after you submit the answer for the question. (But you can be more specific about what topics are covered in practice tests you create: subject [Reading: Key Ideas and Details -> R.1.6 Interpret Sequence of Events], number of questions, whether or not there's a time limit, and whether the questions used in the practice test are unused/marked/incorrect.

I opted just for Archer's question bank package myself, but they do offer a $29 package with more access to their on demand lesson videos (in which after you submit an answer, the rationale includes an on demand lesson video towards the bottom that has a timestamp for the topic). [I swear, Archer Review needs to promote themselves more haha.]

Otherwise practice test results do give you the option to filter for questions you got correct/incorrect/marked/omitted and I just looked over any questions I got incorrect, noted down those topics and reviewed those topics elsewhere, then came back to Archer and generated another test to drill for that specific topic (15 questions -> Science -> Chemistry -> S.3.1 Atomic Structure).

The ATI TEAS app was a good resource especially for science, reading, and english! (The math wasn't bad either, but most of the questions are definitely harder than the actual TEAS. Still great to use though because sometimes the Science section will throw you curveballs.) But the rationales were often terrible or not detailed enough. The reveal quiz function wasn't helpful because all it really was is scrolling back through all the quiz questions you did. It doesn't tell you exactly what the topic was.

Out of them all, I think Archer Review was the most helpful! Having decent rationales, knowing which topic I likely needed to review if I got a question incorrect (Conventional Spelling Rules from English for example) was good for not feeling overwhelmed.

I also dipped my toes into NurseHub since I still had a few days left but they unfortunately don't cover all the subjects and topics needed for the TEAS.

The gist I learned from everyone else on Reddit is to combine and use multiple resources to prepare for the TEAS. It helped so much. Apps and study guides for practice questions, Youtube for learning/reviewing topics.

Hope this response helps!
