Due to the pandemic situation, most of the undergraduate students of the university level are feeling discomfort about learning the quantitative courses online. During the class of quantitative course, seeing the teacher & the teacher's writing, listening to the lecture, and communicating with him online is a very important issue for online learning in a quantitative course. Otherwise, students' learning in quantitative courses will never be clear. That is why I am here to assure you that a student of Business Statistics and Marketing will have the opportunity to be comfortable in their classes. I am used to taking online classes using google. During the online class, I use Facebook messenger, WhatsUp, google Docs, drive, youtube, etc. As a result, neither theoretical nor quantitative courses are being monotonous.
