I have had almost 20 classes with Dibya sir up till now and from personal experience I can tell you his time management and promptness is one that is admirable. He has a really good understanding of the subject, but most importantly a desire and passion to teach, which reflects through his attitude and explainations. He is very different from others because: he will let you as a student learn to solve your doubts using the tools you have (i.e the internet). By doing this, one can still be productive, getting plenty of work done post classes, without the assisting hand of the teacher. This skill is one I found to be very important and time saving. It is no doubt that he exceeds expectations, but there is always room for improvement and little mistakes each one of us make. The only thing I would have appreciated less of is using his phone during the class at times. I have had times where I had a doubt and because he was on whatsapp/phone (perhaps contacting a student or doing somrthing important) his attention wasnt on the class and hence it took time to get back on track and understand my question. Despite this happening maybe once every class or two, I will say it was extremely frustrating, as the time was already restricted from 1 hour 30 minutes to 1 hour. Given these measures you would like the undue attention of the teacher to complete as much work as possible. An additional point i’d like to make is that the pace of the class may feel slow many a times. However, overall many more positives than negatives. The negatives being minor issues which can be fixed or worked around. Undeniably a good teacher. Surpassed my expectations. Would definetly recommend him to you.
