ScholarHat is a nice online institute. I have studied in Several institutes but this is the best among all. The best thing here is Shailendra Sir, the way he teaches is nice, and easy to understand. As per my experience, ScholarHat is the best place for the latest technology learning. I have completed the course ASP.NET Core with MVC and it helped me a lot to understand the concept properly.
It was an excellent experience to learn MERN Stack training from ScholarHat. The courses are top rate and the best part is live instruction, with playback. DNT is one of the modern platforms to learn and equip in the IT Market. I have learned a lot from this training. And really helped to understand all the concepts very well. Thanks again.
This is the first time I have completed the online Training for MVC5 with the angular 2 & 4 development program, earlier I attended classroom training. But now considering the way ScholarHat provides training is awesome. Training Quality is a knowledgeable and well-managed session. The trainer has in-depth knowledge of technology and trying to give his best to share the same. ScholarHat staff are Cooperative and well-behaved.
I would like to thank ScholarHat for providing training on the latest technologies ASP. Net MVC5 with Angular 4 and I got what I was looking for, basically to learn Typescript and Angular 2 & 4. The ScholarHat Staff is very supportive and provides all the help that we used to be required. I appreciate the Trainer's way, of clearing the concept, and deliberating the knowledge to others is excellent. I appreciate the Scholarhat Team backup staff, really amazing. Regular Monitoring sessions via mock-up tests as well as assignments, which proved of great help at the time of project development, paying attention individually is Great. The study material is also easy to understand and the video can be downloaded after every session. I strongly recommend ScholarHat, even if they provide WhatsApp for the resolution of any technical query. Thanks for standing with me for all my concerns.
Shailendra sir has in-depth and sound knowledge of .NET and related stack. His way of conducting sessions and handling doubts/queries is awesome.
