My name is Fahad Akhtar, I am from Pakistan Karachi, pre-calculus: functions was my first course in coursera, where I learnt more deeply than before, I recommend this course to complete it first for those, who want to learn calculus. thanks
Theory part is not covered properly in video but textbased stuffs where fine enough and well explained.
Videos just contain alogritums on how to solve certain kinds of problem rather then a full view of what kind of thinking and aproch we should have.
thank you very much

It's a good course for recall school algebra. A lot of thanks to teachers.
