Not here, these are different classes, it might be because in my country engineering careers last 5 years instead of 4.

I should hope that with all that studying, you get a career that lasts more than just five years!! :wink:

I think I didnā€™t explain myself correctly, we go to undergraduate school for 5 years instead of 4.

I understood. I was speaking jokinglyā€“hence the winky emoji.

BTW, what country are you from?

Iā€™m from Colombia :slight_smile:

What are you talking about? Learning probability and statistics requires knowledge of calculus, especially if you want a deep understanding of these subjects. Yes, you can learn probability and statistics without calculus, but thatā€™s high school level stuff.

Most universities have a 3-part calculus series ā€“ Calculus I deals with single-variable calculus, Calculus II with multivariable calculus and Calculus III with differential equations. Differential equations is a pretty big field of mathematics, so an entire semester is usually devoted to it.
