My #22 course certificate from Coursera

Single Variable Calculus
University of Pennsylvania

This course is AMAZING! It probably is the BEST Calculus course you can find on the internet. It is also a “marathon” containing 5 parts, 50+ lectures costing me almost 1/2 year to finish all of them. I felt hardness, pain, joy and confidence. I wish I could have this course when I was in college – but it’s never too late. Thank you Prof Ghrist and Coursera. You are wonderful!
