Attempting to create an app for my coursework... Please HELP!

Hello,

My name is Agnes and I'm currently studying A Level Computing. For our coursework we have to create a Visual Basic program but I wanted to do something different and since I always wanted to make an app I thought this would be a great idea to do for my coursework... Wrong!

I did not realise how hard it is and I'm really lost.. I'm attempting to make an calendar/to-do list app specifically for my college where students can enter their timetable, homework, coursework dates as well as upcoming exams...

IF ANY ONE CAN HELP ME I'D REALLYYY APPRECIATE IT.

My teacher doesn't think I can manage but I really want to prove him wrong.. please help me 🙂

Massive thanks in advance!!!
