How hard is it to balance MTech at IIT Bombay with online courses?

I’m planning to join MTech at IIT Bombay and was wondering how manageable it is to juggle the academic workload with online courses (like certifications, upskilling, etc.). For those who’ve been through it — how did you balance both? Did the online courses actually help with your MTech work, or did they just add to the stress? Any insights, tips, or personal experiences would be super helpful!
