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."

After I signed up and started the class, I was disappointed to see that there are only 2 video lectures for the entire program. After starting and going through the first week, I realized that I could just as well have checked a book out from the local library and gotten the same information. I was hoping for an instructor led course. I will look elsewhere - You Tube or EdX may have a more engaging course.

O curso de Introduction to Logic oferecido pela Stanford University é excelente! De fato ele não é um curso introdutório, vai muito além com uma abordagem completa sobre o assunto. Os exercícios são muito bons e ajudam a desenvolver habilidades analíticas. Com certeza é um curso que irei recomendar.

Todo es en una página externa que parece de hace 20 años y no hay videos, solo texto. Pero eso es cuestión de gustos, cursé toda la primera semana pero no me habilita a pasar a la segunda por que la página externa no funciona como debería y no marca como concluida la primera...

Course is fine but there isn't much material for INTRODUCTION. Good Math Skills Required.

Excelente

The name don't lie: this is a introduction. There're some funny examples and I recomend for those who that are beginners in Logic.

I feel like some things could have been explained better, maybe a better description of how the fitch tool worked. Other than that, it was a great course!

Wonderful course! Thanks a lot!

Unfortunately there are several problems with the external tool, although the course is very complete, the presentations of the slides are very short, they would need more development, to be more friendly with the reader.

After the chapter 7 explanations may appear rather vague, that hampers understanding

While I did learn a great deal with this course, I feel like it's not well made. No videos is clearly a minus, but that's just a nitpick. The biggest problem are the graded exercises. Some of the fitch exercises are ridiculously complicated until you reach the last sessions, where you can literally just write the goal you want without even reading the exercise.

Excellent introduction to logic. The exercises really help with the understanding.

The course is great, but the grading system is always broken.

no video, only external link

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

Very solid one.
