Data Science Course

Currently enrolled in a Data Science Course which is IBM certified and I am in 12th class will end in September I have skipped almost 2-3 months of classes but I still know what happened in that time period and I am still trying to cover up my backlog as its a pain in ass situation for me and I am still not sure if this course will be a waste of a gem for my carrier and I need guidance if my jee not clears what else I can do in this field
