Question Bank Web Application -- 2

We are a team of students, and we want to create a question bank website (or technically a web application) similar to something like Uworld, Amboss, etc. (if you’re familiar with those). The idea is simple : we want the user to be able to go on our website choose the semester he/she wants to purchase, and for each semester there are multiple classes, and for each class multiple lectures. We want the user to have the flexibility of choosing questions to study based on the lecture he/she finished studying. I will attach some concept images we have for how we want each page of the website to look like.

The project timeline is flexible, but I hope to have a working prototype within 2-3 months.
