There is no doubt about the depth of knowledge of sir. But he is not capable to deliver his speech to students appropriately. A simple lesson is made more complex in his lecture. Doesn’t give lecture slides. Just take scrnshot from Indian different website and deliver his speech. No consequences in his lecture. After paying the highest attention in his class, it didn’t get in students mind. Only CGPA is not the criteria for a teacher. High CGA not always indicates a good teacher.
