Thanks to Hari Sir, I cleared both the group in first attempt even after 5 years of break from studies. Conceptual understanding is very important for passing any professional exam. How much ever problem you do, without understanding the concept clearly you cannot pass. Hari Sir helped me a lot in understanding the concepts clearly and he also correlated his practical experiences to the subject. His stimulation technique is amazing. I could score at least 20 to 25 questions through the techniques. Thanks once again to Hari Sir, Madam and Emerge team.
