I am happy to announce that I have finished the 1st half of my Selenium course with Sundar and that I highly recommend him for any of your future students. He is extremely knowledge about technology, QA, and how everything works together as a system to give you an holistic view on how what your learning will impact your entire environment. There is not one question he could not answer (and I asked many questions) and he is very patient when it comes to answering them. More importantly the best way to utilize his training is to be in the field at the same time you are taking the class. You can attempt use some of the things he teaches on the job and I am sure they will work. Give it a try, and if you some how get stumped ask him and I am sure he will gladly assist.
