Practise Platform with blank space for word processor and excel type questions

I can’t seem to find a blank area to work on for section C question types as I struggle with the system for the ACCA PM paper. Every time I try and login onto myacca profile under the practise platform it keeps loading and nothing happens.

Would someone please provide a link of where I’d be able to practise questions under the word processor and excel?

Thanks,
Becky
