Thanks God for the successful completion of my study. I really appreciate Prof. Hariharan’s dedication and effort who has worked hard like a caring father who is eager to see the success of his children. The deep knowledge he has in the subject matter together with his systematic way of presenting was vital for my success. Furthermore attending classes, efficient utilization of time, practicing as much MCQ as possible on the Wiley test bank and the books, attending the mock exams are the key for my success.
