Udemy is the leading online learning platform according to our survey on the best online learning platforms for 2021, and as predicted from google search trends. Udemy has made some of the online science courses freely accessible; most of the courses belong to basic sciences, which can be useful for high school students/ teachers/ or those who want to clear basic concepts in Biology, Physics, and Chemistry.
We have made available those free online science courses in the list below. You can enroll in any of the free course and enjoy complete access to the video content; however, for getting a certificate of completion, instructor Q & A, and for instructor’s message, you will have to pay at the end of the course or at any time during the course. Otherwise, the course content is freely accessible.
Note: While the free online science courses were listed, they were freely accessible. It might be possible that some of the courses in the list are no more free of charge because they were on promotion when we listed them.
