No good words can be told about him. I am just mentioning a few things I noticed this semester:

1. He teaches things in 3/4 classes that is actually a matter of 30 minutes.

2. He insists on following his way of coding and gets angry if anyone doesn't write code as he has showed. Truth to be told, programming is an open field. The outcome is important, not the path. But he forbids students to follow any other ways (only reason is, he doesn't understand and know those ways)

3. He insists students to buy and read his books. He is actually trying to sell his books to the students. Again, most probably because not many other people will buy them.

4. (Banglish) MMJR telano pochondo kore. J taake beshi telabe, taake beshi number dey. J telaite parbe na, taake number o dey na.

5. He encourages students to do research under his supervision. He tells them to copy different chinese research papers and publish them by transforming the sentences so that it would look like a new research paper.

6. He calls students to his room and tells them to take research under him even if they have already completed research. Such meetings, I heard from some of my female friends, they became afraid because he would conduct these meetings in his room with the door locked from inside without anyone else.

In conclusion, as mentioned above,
a) He is biased to the students who can praise him to his expectation.

b) He demonstrated a basic point of view of HTML and told us that there's  nothing to learn about it.

c) He copied a few lines of JavaScript code from internet and showed it to the class and declared that JavaScript is also complete. IT IS NOT. JavaScript is a vast ocean.

d) This is only one course, people don't speak up about these in other courses. Because all they want is to get good marks. I am scared about the department as long as he keeps going like this.
