since the Section 2.5 - Satisfaction and on it doesn`t score any passed lessons or assignements, there is always an error "Unfortunately due to an error, your score was not recorded."

This course was so helpful. I think I now understand the fundamentals of mathematical logic. I truly recommend this course to anyone who is interested in studying logic!

I have found it not extremely clear in the latter part of the course, perhaps more examples would help. Most of the section 1 to 9 (from propositional logic to relational logic and Herbrand logic) are quite clear and straight-forward. An historical background of who, when and why theories and computing methodologies were elaborated would certainly increase interest.

A pain if completing this course when the session not started yet. Without forum talking about solutions to exercise, usually in some exercises you could only stare at the screen for several hours, fell in deep despair, and eventually came up an answer by luck. Not a good experience, but the material is good though, if not considering the difficutly of understanding the text in the later lessons

Good review for those who have studied quantified logic at any level. The Fitch system is fun and easy to use - especially where it automatically cites the inference rules for you. Having done many informal inductive proofs, I found the extension of first-order logic to include induction particularly interesting - if intensely tedious in application.

i loved every second of it , i'm at week 2 right now

you will learn how to think like a mathematician

Good structure. Helped a lot with my university unit. It would be great if we can get sample solutions for our exercises.

It is literally a book. Transcripted into an online 'course'.

Very very good course
