Dashboard

On the first page, you can see the time, and four other main pages: schedule, recipes, habit tracker and classes. In this last one, you can add all your assignments and classify them by subject, date, and add your marks once you have it; you can also co to another page called grades, where you can add all your assignments and exams and fill the other information and the table will calculate the expected grade for that subject.
Next, under the gallery view you have a weekly planner, basically a to-do list for every day of the week.
Lastly, if you scroll down you'll see a calendar with two views available; a table view where you can add all your appointments, and a calendar view of the week (you can change it to month) where you can see all the appointments.

Of course, use the template as you wish, change everything you need to fit your preferences and I hope you enjoy.
