It will be same like 2023? 207/270 A*?
Had no clue what to write for that last 6 marker 💀

I wrote about wind opposing and changing v as my independant variable and measuring velocity of object as well as keeping mass constant

I spoke about adding another voltmeter in parallel to the power supply to measure internal resistance as it could lead to a systematic error (I was waffling out my arse)

I spoke about current only flowing one way so ensure ur voltmeter is connected to the right pannel

Nah doubt it cos of paper 1. 2023 was easy

I talked about air resistance. Kept mass constant and then using the variable speed fan increase her speed. Complete waffle

Yh man hopefully OCR don’t be silly and make grade boundaries like last year after the atrocity of paper 1

I think it’s 200 for a star

Isn’t that what the diode’s for 😭

Definitely less than 200 for a*
Paper 1 - 66/110
Paper 2 -80/100
Paper 3 -49/70
195/270 A* I think so.

I just said have a switch to prevent components from heating up.

Ppl could measure 0 readings that’s y

What was the shape of your graph btw, I did an exponential and only allowed the current to be +ve so it started at the y intercept and went up from there

Omg, I forgot striking potentials exist imma lose a mark noooo
