No super or subscript notation when reading problems makes it difficult to see what exactly is being asked or conveyed. Just use parentheses and the carrot symbol, it’s not that hard (3x^2) or even 10mm^3 - see?? Very poorly executed. **Developer response:** You are correct in your conclusion regarding the module you have used. However, I have set a pop-up notification relating to all modules which are not complete. This states clearly that they are designed to show functionality of the app only. The module you reviewed is not to be used for study. In any question bank consisting of 8,000+ questions, there will always be sub-standard questions (even EASA and Part-147 organisations have them). For the modules which are available as an in app purchase, I have provided a feedback link. ### 3/5 — Trouble opening exam *2021-09-17, version 3.1.4* I can’t seem to find any practice exam for module 6? ### 5/5 — The Best So Far *2020-06-18, version 3.1.4* This is the best Part 66 revision aid I have used online and well worth purchasing the add ons. There are loads of practice exams which allow you to review your answers it also gives feedback on which chapters of the module you need to improve on, and the flash cards are great for revision. I queried a couple of exam questions via the in-app email link and got a detailed explanation within minutes from one of the Part-147 instructors which is probably the most impressive thing with this app. ### 5/5 — Easy check of my knowledge *2020-06-10, version 3.1.4* This app helps a lot with checking your level of knowledge for the EASA exams ### 5/5 — Best study app for part 66 *2020-05-27, version 3.1.1* Awesome app that’s the easiest way to study for your part 66 licensing exams. ## Frequently asked questions about Part66 ### What EASA Part 66 modules does Part66-Engineer cover?
