  • Offline courses rely on the locally available teachers, which are not always best quality.
  • They also carry with themselves a constraint of time and location.
  • If you are a working professional you can't join one.
  • Similarly, if you are in a small town you can't join any good institute.
  • GATESchool brings you the best of academics and training to your doorstep.
  • It's very simple.
  • Choose the package you want to get.
  • Make the payment and you are done!
  • Within next 30 minutes you will get the login and password for the online access and within a week you will get the pendrive.
  • There are a number of ways to do that.
  • Firstly, you will be getting a mentor who will be a subject matter expert and will be calling you regularly.
  • He/she will be able to address your doubts.
  • Apart from that, you will be added to a WhatsApp group, which will be led by a mentor, who will be solving the doubts on a daily basis.
  • Live classes is an opportunity to interact with a teacher live.
  • They will be conducted online on a predecided topic.
  • You can suggest the topic you find difficult for the live class topic and also ask questions in real time.
  • Mock tests will be online and will be conducted as per the GATE pattern.
  • They will be timed and will have the marking scheme same as the real GATE exam.
