Everyone ready for tomorrow???
Hopefully tomorrow paper should be easy
Any idea on what topics are very likely to come uptomorrow?
I'm so cooked **** that paper
How was the paper?

Had no clue what to write for that last 6 marker 💀

Mid but not the best.
Timing was an issue.
What did u get for the percentage uncertainty in gradient for temperature?

Absolutely beautiful other than that last 6 marker, absolutely ate my arse bare and all I could waffle about was trying to solve for some constant through the ratio of their values. Barely could think of a practical technique so max 1 mark on it 😭😭

I got 13% and for the value of C was 16.9%, I didn’t know whether to leave it at 3sf so just took the risk, they’re normally not strict on uncertainty sf

i got 7.9% I just did gradient of best fit and worst fit.

Oh same, did I mess up im scared now 😭

Not a clue man also the question on Electricity did you talk about using a switch and a variable resistor.

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)

Also if u don’t convert g into kg do you lose all marks. Or do u still get some working out marks

I thought about the variable resistor but I said it was used as a control variable to take a fixed share of the p.d through the experiment so didn’t talk ab it

Most likely POT error, they’re quite weird with those so just pray 😭
