Startup Idea : Share study resource

I want to utilise the study resource of any grade student to other student to make understanding easy and helpful. I want to collect the notebook, project, resource, question from examination anything that could be helpful to the student working out same platform and share it in website. Question and answer written in notebook can be scanned or take photo and later edit it accordingly. Not everyone has opportunity to buy every resource just to pass an examination so i just want to resolve the problem i faced as a student. Any help, recommendation or suggestion for change and update is appreciated. Thank you
