Dear Admin, Thanks a lot for your wonderful work. I really appreciate your work. I wish if pdf format was available.it will provide more comfort to learn the topics with more ease. Another thing that I felt that contents provided are awesome but at the GATE level you need to improve a lot...lots of materials should be added so that for those who are preparing for GATE or other Engineering competitive Exams can get much more benefits. Thanks again... Wish you and all the members, all the best for your future. Regards Vishal S.
