Need help with college

Hi I'm 21M, currently studying applied statistics and data analytics from MIT-WPU. My professor has decided that we need to do a MOOC course or any course with certificate, I'm not able to find any courses that are offering a certificate, does anyone over here know a method where I can procure a certificate or a way I can get free courses with certification. Also to note, college is not at all offering any paid subscription to any websites and want us to pay out of our own pockets and the courses recommended are very expensive (The IBM data science ones are 99$) which I personally don't want to spend so much for such a simple course. Any sort of help is needed as this is very last minute and I need to submit before second week of March, the subjects I require are - Data science, Machine learning, Programming, Analytics, etc. Thank you in advance
