yes, if it's a minor change I just put comments on what you have to do and what you don't.

for example interfaces were taken out, but some of the concepts are still used in inheritance, so I will just mention that you don't have to be able to write interfaces yourself.

if there is a new section not covered by the current lecture, I will add them on or reshoot the portions changed. 

do remember that the 2020 changes will not remain in place, since they were temporary measures for the covid-19 pandemic.
