I have just completed your 18.01 course and am now starting Multivariable Calculus. This is just as clear and well taught as the previous course. I think we have entered a new age of higher education where institutions such as MIT take the lead to post entire courses online free for all of whom are willing to learn. I look forward to seeing more advance courses in Mathematics, Physics and indeed all other disciplines uploaded in the future. From the bottom of my heart, thank you MIT.####[['course', 'Course_General_Feedback', 'POS'], ['Multivariable Calculus', 'Course_General_Feedback', 'NEU'], ['MIT', 'Other', 'POS']]
