    It was highly interactive course. As a student who just completed his 1st year B.Tech in Electrical and Electronics Engineering, this course was a breath of fresh air, as it followed a different path of teaching, swaying from the traditional way of how courses are made. i found the audio interactive sessions really interesting, as it was highly interactive, and made the course more interesting. Apart from this, gaining more knowledge on amplifiers and other circuits was really great too. an overall great course, and highly recommended.
