What did you talk about for your English GCSE speakingWatch
I did about dementia as I had recently lost my grandma to it at that point. Just do something you’re passionate about. If it makes you feel better, I’m in year 13 and I have never been asked about my speaking once.
But you can pretty much talk about anything
General advise I can give is that if you are asked to present on quite literally anything take the p**s and do something utterly ridiculous.
On my work experience, I was asked to give a presentation on the best pastry I had ever eaten on the spot, no preparation, no powerpoint, nothing. The purpose was to see who had an intuitive grasp of the skills required to present. A powerpoint is not a presentation; it is a tool to aid one. Always remember that and as I said before speaking about weird things actually gives me much more confidence when presenting.
For example why not "Retaking Facebook: Should all account ages over 40 be banned?"
I got a distinction with that topic
I did mine on the impact of smartphones on society. I didn't do much research into it, but I presented with confidence as I have good public speaking skills, so it was that which actually impressed my teacher and earned me a distinction
