My laptop died during one of my exams.

Damn. I had a focal aware sezuire during my exam

I type my exams due to an illness.
I took one of my GCSE exams a while back and my laptop died at the end of the exam. I asked for a charger 30 minutes before it died and asked at least twice. The invigilator did not take action until my laptop fully died. I think I lost some work due to not saving. The invigilators then took some time to find a charger and I was given 5 minutes extra. However, the exam hall was pretty loud with everyone leaving by the time I was given a charger, and I feel I was disadvantaged. The invigilator said she would make it right and notify my school's exam officer.
I get my results in less than a month, but I cant help but feel a sense of dread that my grade will be impacted because of this.
What should I do to remedy the situation?

I seriously doubt there’s anything you can do now as it probably would be a little bit late to inform the exams office at your school. However, since the invigilator did say at the time they would notify the exams officer, you likely will be given some form of compensation.
The best thing you can do right now is find a distraction, since you have finished. Why not reward yourself for getting through GCSEs by taking yourself out for a day, having a movie night or whatever floats your boat / is doable.
I do believe it is possible to appeal grades so nearer the time of results day, if you are still worried, it might be sensible to familiarise yourself with such procedures by reading the relevant pages on the exam board’s website. If your grade does turn out to be negatively impacted as feared, you are at least prepared to do something about it. If not, then that’s amazing and taking those extra precautions didn’t hurt.

If your exams officer applied for special consideration due to the disruption then the most you’ll get is 1-2% extra marks, with marks being rounded up I think. Eg if your paper was worth 80 marks and you got 1% extra it would be 1 extra mark rather than 0.8. Best of luck for results day

it's of your total not the paper total
If someone got 60/80 they'd be given 0.6 on top
idk about rounding up though as sometimes you can get decimal scores due to weighting (I did for Spanish)

I dont think this is correct, they give you a percentage (1-5%) of ‘the total raw marks available in the component concerned’. I was informed by my school that due to circumstances in one of my gcse papers we would as a cohort hopefully receive 2% extra marks on an 80 mark paper- so 2 extra marks.
Happy to be corrected but the jcq regs and what i was told at school suggest that it is of the total marks available, not the mark achieve. Have a nice day
