Rahul Krishna

One of the best, patient and qualified tutor in the city to get in line with strong basics.



Vijayalakshmi Mam gave more practical knowledge rather than just the theoretical examples. She gave personal attention and proceeded further only if the previous topics were completely understood. I would strongly recommend the training in Core Jave and Unix.
