OCR 21st Century GCSE Science - P1 P2 P3 - 24th May 2017

Honestly I don't remember. I just remember multiplying things together and converting things into units throughout the entire paper 😂😂 This exam was legit practice for my maths exam tomorrow!!

Same!!! I thought I was the only one that enjoyed it because everyone at my school was complaining at how difficult it was but to be fair it didn't include quite a lot of mathematical calculations!

Anyways, what did you write for the first six maker about the stares , galaxies and the elements?
Also is the last few calculations did you use the Power= Current x voltage to find the power and then converted it to KW and converted the seconds to hours?

In the first six marker I talked about random stuff for stars that should get me 2 or 3 marks and then about redshift in galaxies and how that proves space is expanding, which should get me 3 marks hopefully.

For the questions on the last page, I got 1.15 kWh and 540J.

For that question, I converted the megabits to bits (21 000 000 bits in total) and ended up getting 274.3 seconds I think.

I really don't think I did very well in that paper 😭 what did you get for the questions you had to convert it to nanometres to one significant figure? I got like 5×10^-16 which is obviously wrong

What did u get for the part before that when it asked you about the information? I got 4.3 seconds because I got 90000000 for the part before it and divided it 21000000 ehich gave me 4.3 seconds.

I got something around 5 billion for part a.

Would you be able to remember the question or parts of it? My mind is playing games with me so I am unable to think right now :x

Ah. I remember that I got 5 760 000 000 as the number of bits and then divided it by 21 000 000.

Yup, I deffo got that question wrong then lol -_-' Funny how I thought I was right the entire time. But how did u get 5.76billion?

Sorry, but I can't remember anything apart from multiplying a few things together.
