Hello.My course completion was previously 42% now it has gone to 31% and now i can see that some videos have just been not there previously and the sequence has also changed like after logistic regression it was NLTK and naive bayes now its showing feature selection and PCA. Whats happening?
Error in course contents
Hey @Sid10, there’s nothing to worry about. No videos have been deleted from the course. The modification that is done is just that some more modules and topics have been added to the course for your better learning experience. The course now covers major libraries like seaborn , important concepts like feature selection, PCA(principle component analysis) , etc. These topic are very good. I would suggest you to go through them and gain the best of those videos.
Happy Learning 
Yeah but actually many videos which i have seen and was completed has again marked unread and hence my course progress has went down
No worries you can just fast forward them to mark them as completed. Sorry for the inconvenience.
Happy Learning
