The problem Note Maker solves

In the lockdown period all our classes are being held online and so the teachers are using slides and presentation for teaching and students instead of taking down the notes are clicking photos or taking screenshot of the content and then they are sharing those photos over whatsapp or any other platform, but due to chats to go back to the notes is quite time taking as you have to scroll thousand's of msseges(atleast in my calss group this happens) so what this web app does is that you just have to sign up on the website choose your class and start posting all your notes their , and the same can be done by your classmates and you can view all the notes shared by your classmates( ones who chosen the same class as you did ) also if you find something wrong in the notes you can delete them and add any suggestion to someone other's note by commenting on their notes the notes you should upload can be of any form (vdo,pdf or image) and you can view them enlarged , comments can only be deleted by the user who created it and this is all our simple web app

Challenges we ran into
