Much appreciation for these videos, Dr. Califf. My professor now could take some notes. I've never before been so lost following a 3-hour lecture only to feel confident enough for a test 15 minutes later

wow, very good video! the only point where i missed a programming example was when you were talking about nonterminals at first but being new to this you gave the perfect intro! thank you!

This helped me understand the topic very well, I was really struggling to understand the basics of this in my class. Thank you very much for the video!

I just want to say you are amazing and saved my midterm grade :)

Very clear explanation and a good presentation! Exactly what I needed to help me grasp the concept of BNF quickly and intuitively

Hard to catchup if you're not familiair with certain phrases, but it helps me out understanding less good described study material of the course I'm taking...👍🏻

This was amazingly helpful. You gave a nice overview of grammar and how to describe it with BNF. Thank you for video.

[mhamadkamel]

thank you! you are amazing. this video was one of the easiest to understand. I have a question: is it possible to make a rule for another language that has a different syntax and grammar structure from English? for example in English the determiner which is "the" is in front of the noun: the apple. but in Kurdish the determiner is behind a noun: Sewaka. sew: apple, aka:the. can we set a rule for these type of grammar where a noun is followed by a determiner?

Excellent Video. Excellent tutoring. Thank you. (Although I do feel that Panini could have had a mention even if just to illustrate how long people have been thinking about this stuff)
