Great course, great instructor. It really worth if you want to improve your programmer skills. You will see some of the beauties in CS: lots of wisdom in a few lines of code. I needed more hours than expected to finish, especially with some really challenging problems, but I enjoyed every minute.

This is a terrific but rigorous aerodynamics course. Your profile must be closer to a mathematician than a pilot. Math-intensive and time-intensive. Most of the material is in text format (unusual in modern MOOCs) and student have to process by himself, as professors do in the on-campus version. Course Notes becomes a 538 pages PDF document (including problems and some edX web stuff). It is an exceptional quality document, a beta version of a future aerodynamics best seller. On the other side, every problem is profuse commented in video lectures. Only 2 attempts for every homework and exams. It contradicts the MOOC's law of "fail forward", but you will survive (at the cost of lots of hours). You have all a week to solve the exams.

This is the companion of "16.101x: Introduction to Aerodynamics" for the first edX XSeries, and has a lot in common: even more math-intensive and more time- intensive. Your profile must be closer to a mathematician than a pilot. It differs that most of the matter are taught by video lectures, but solutions are only a text excerpt. It's a graduate level course, be prepared: the first problem you will see about an issue... is your homework. The second, your exam. Only 2 attempts. Stressful, but affordable... if you can invert lots of hours. Great textbook, very useful for learning and will be a nice reference in the future. You can access but not download (book is publised by MIT Press). With some perspective, I look to Aerodynamics like the art of simplification: you have an unaffordable math model, but you will extract some conclusions, solve and even design analytically. Unfortunately you will neither use any numerical tool nor design any airfoil. Mark Drela is an authority in Aerodynamics, author of books (including the textbook of the same title) and software developer. He demonstrates to be an exceptional lecturer, making easy the hardest subject. Absolutelly one of the top ten MOOC's professors IMO. You have all a week to solve each of the three exams. Interesting wind tunnel lab also takes a week.

El patio feo de todos los cursos online (MOOC) que he hecho. Básicamente el profesor Sandoval se limita a darte 4 pinceladas en sus breves presentaciones, y te invita a mirar el material complementario. Éste consiste sobre todo en una fotocopias, de mala calidad, de un libro descatalogado. Los ejercicios son unos casos prácticos, bastante difusos a mi entender, sobre el tema. La corrección, al ser texto con tus ideas, se hace entre iguales (peer assessment): fue un desastre porque la misma gente que no se molestaba en hacer los ejercicios no se molestaba en corregir los de otros... acabamos autocalificándonos en un 50%. La soluciones consistían sólo en enumerar las ideas principales. Pocos días después de la finalización del curso, sin aviso previo, desapareció por completo: material, vídeos, foro de discusión, ejercicios propios y soluciones... No sé si es algo habitual en Coursera (no he repetido) pero sigue pareciéndome inaudito. En general la experiencia me recuerda más a algunos profesores mediocres que tuve en la Universidad española, que a los cursos impecables que he hecho en edX o Udacity (sobre informática, electrónica y aerodinámica que, he de admitir, son materias que me atraen bastante más). Pese a lo dicho, terminé el curso porque sólo duró 6 semanas, y aprendí alguna cosa que puede que me sea útil, sobre todo en los vídeos de los "artistas invitados".

Very interesting course, you will learn a lot very fast. (Sometimes too fast: be prepared to code till late to accomplish due dates.) Pacman environment, inside you have to program homeworks algorithms, is simply a work of art. Excellent lectures. In the cons: you will see only some pseudocode lines at lectures, but you have to type complete OOP Python code to solve the homeworks. Code solutions are forbidden in discussion forum: if you can't solve the exercise, probably you will feel alone... Final exam is just test questions, your programming skills could not score 1 point. Still waiting for the second part of the course... 14 months after completion of CS188.1x

This is a must in computer science MOOCs. You will love programing and you will fall in love with Python. Quizzes are not too difficult, but you have some challenging exercises that will really squeeze your brain. Great forum, you will learn a lot from other students (no top secret about solutions as in other courses).

This is an basic course, under graduate level, but with some fun concepts even if you have some knowledge about statistics. Sebastian Thrun, founder of Udacity, demonstrates to be a great instructor.

I took the pilot course, just in the edX born. Course is impressive, the prototype what a MOOC should be: exceptional professor (Anant Agarwal, actual edX president), complete material, challenging homework and affordable exams. You will learn a lot and you will enjoy a lot, whatever you are an expert or new with electronics.
