Things needed for a Celta course: (someone please reply)

Hi,
I'm about to start my Celta Course in 2 days.😲
I know this may sound silly, but what do I need to take with me besides the course books?
I already have-

1- Pens
2- Notebooks
3- eraser/pencils
4- highlighter
5- folder(s)- how many?

Did I miss something?

Thanks a bunch.
