it has a calendar which is a database which you could i guess convert it to a grade calculator on another page, the pages in the big rectangles are easily accessible too! (add a picture of what you want the thumbnail to be on the page it links to)! if you do the ib, there's a countdown to the ib for 2025 april 23 but it can be used for igcses/gcses as well (may/june!) hope you like it!
