NAVY GSM1 is one of the best on the market because it is bibliography oriented. It only focuses on chapters mentioned in your Exam'S Bibliography.The app has more than 1000 questions on various topics including the possibility of studying specific sections (FO/LO Sys, PMK, Aux Support, Engineering Admin, GTG Sys, etc.).The application doesn't require internet and can be used to study while underway.If you find any mistake, typos or bugs, feel free to contact me at and I will gladly take into consideration your remarks on the next application upgrade.If you have any issues with the app, please do not leave a bad review.I will fix the issue on my return and make sure you have the updated version for free.Counting on your understanding.Thanks.
