イリノイ大学アーバナ・シャンペーン校（University of Illinois at Urbana-Champaign） による Planet Earth...and You! の受講者のレビューおよびフィードバック

Very good information - I loved the Google Earth Labs you guys set up for us. Really useful and a fun way to connect knowledge with real life.

Nice entry to geology.

You have to purchase (50 dollars!) the entire course in order to do the quizzes and assignments....that ruined the entire course for me.

excelente curso

very interesting to me it gives very basic information.

Great course, despite the glitches in the links, etc., which seemed to be outdated. i really gained little from the forum.

Very interesting and interactive course.

Th course is really great and rich and what I rally liked is the practical work on google earth.

Excellent course! Very informative without being tedious. Clear and concise delivery and illustrations. Would recommend!

This is the second time that I took this course. It was more in depth in topics than the original course, and I enjoyed it. Good presentation. Thank you.

Me dió una fundamentación en las ciencias de la tierra. Bien explicado e informativo

An incredible course with incredible teachers and full of new and complex information. It was a dream to study this subject and now I'm trained and certified. Thank you for this opportunity to share and acquire more knowledge on this subject that is increasingly important to know, after all, the world needs to be studied and known so that our decisions are rational and not harmful to the environment. Finally, I hope that someday I will be able to study at the University of Illinois.

I love this course, though I have only audited it - I am going to do the whole course when I have more time! Professor Marshak teaches with ease, engages students and makes geology a passionate subject matter. I would love to see more courses by Him covering the other chapters of his book Essentials of geology. Highly recommended for anyone who wants to understand science in action.

Very clear and easy to understand even if you're note native english speaker.

It would have been great to get the answers to the quizzes even in the free version.
