 Hello everyone, my name is Sonu Munjar and I am post graduate in biochemistry. I have vast experience in teaching in various reputed institutes. I have this continuous urge of learning throughout my life and NPTEL gave me this opportunity to pursue my passion and I really enjoyed it. So far I have attempted more than 15 courses and I have begged silver and gold in almost all the courses. I was even declared absolute topper in two of the courses. My journey with NPTEL has been really enlightening and enjoyable and I am determined to continue this in the future. I wish all the best to all the NPTEL candidates and I wish them success in their future endeavors. Thanks.
