School website design

Hello all I am developing a school website for my college project with help of my friend but I'm confused on how to make one like.
I want to add things like course egistration, online fees payment, checking results etc.
I have got a example website like which I want to design which is Fpo.edu.ng
also I have got so many udemy courses from BHW but not finding suitable.

Is there anyone who can help me with better course on developing like a school website course.
It's urjent please please please!!
Thank you.

This is rather complex, as some schools pay several thousands of dollars to get their sites done. So good luck.

You need a lot of experience and knowledge to do that. A lot of young people like you create a wrong picture about web development in the beginning. You have learned some basic HTML and CSS, learned how to edit templates and you think you can create a website for every organization?
The project that you and your friend decided to implement requires a decent knowledge in not only HTML and CSS, but PHP(most likely), Javascript and JS frameworks and the most important - databases including SQL and MySQL, Oracle XE or other software.
After you master the above mentioned languages and software, then you may offer your services to others. You cannot create a serious website for your school if you don't know how to create an ERD for the project. I bet you don't even know what ERD is, am I right?

just putting this here

I have got a pohect to complete I am not offering or this is not a kind of service. Yes I know only html and Css with some knowledge on WordPress. And I don't know on how these MySQL or other platform works.
Anyways that's why I asked if someone have a decent udemy or something similar course where I can learn this.
Thanks for all ya comments.

Get the Lynda PHP and MySQL Essential Training course (torrent probably). then learn how to build a user registration system. It's based on PHP OOP but the instructor is great at explaining things. Doing this, you'll basically learn how to add/edit/update data from the database.

Once you complete the course I think you've got what it needs. It should be simple to create different tables for courses, results, fees, users and then just querying the database to relate with each other based on what information should be displayed on the page.

Good Luck!
