I am preparing for the upsc exam from last two year. For the regularly online study I use many app just like IASbaba. It is one of the best app for the online preparation. On this site they update regularly test and the mcq. The quality of the questions are very good and taff. Many time lot of question they asked which is already covered in this app. Information related to every topic they covered veey well.
All the topic related to the UPSC and other competitive exam they covered better way in this app. So according to me its very usefull app for the competitive exam. THANK YOU.
