The trainer is profound in the .NET field, has strong knowledge, and the concept is clear. I wanted to do the course, which makes me an expert in .NET & I can say this is possible only on Trainer’s expertise. The course content of .NET Solution Architect is informative and assertive. Conveyed sufficient time to elaborate on the doubts. ScholarHat is a platform where I learnt so many things and technologies that, I got in touch with .NET Microservices, and Azure DevOps. I am extremely happy with the training method, and the trainer's deep knowledge is very rich and powerful. I was able to learn the concepts and grasp the subject better.

Course gives insight to real life exposure and platform to enhance the overall project management skills of .NET Development Program. Training session is quite interactive, and explained with lots of examples, looking forward to the rest of the training. Actually I heard first time for live session, when ScholarHat member called me and awarded me about the LIVE Interactive class. Demo was really fruitful and very clearly explained. ScholarHat staff is energetic to ensure us, providing appropriate knowledge at any time. Real time project helped me to understand basic concept idea. The entire session was so engaging & interviewing. The concepts and content of Course dramatically structured in systematic way. Thanks again to Trainer, enhancing my skills in simple n steady way, with perfect live examples.
