Would take again

Prof Koshy is one of those rare professors who genuinely care about how his students do in his class and their well-being. Exams are tough, but as long as you are studying and attending tutoring sessions (he highly encourages it because even he knows chemistry is a tough subject), you will do fine in the class.
