Natural Sciences Applicants Cambridge 2025

In anticipation of applications next year.
Which A levels do you take?
Which colleges are you looking to apply to?
What are you gcses?
What are your predicted grades (if you have them)?
+Any other fun facts about yourself

Hi! I’ll be the first. I take maths further maths chem and physics. I have 9 nines, an 8 and a 7 at gcse, I’m looking to apply for physical natural sciences at Jesus, Christ’s or corpus. I have 4A*s predicted and a fun fact would be that I’ve gone to 15 metres below the sea without scuba equipment (free diving). I’m obsessed with all things natural sciences so very happy to talk to people about it!

Also do you have to hold your breath when you go 15m under? Is there a big pressure difference?

Nice to meet you! Yes there’s a large difference in pressure. For every metre or so you go down you must equalise by holding your nose and forcing air through your sinuses into your ears (you can try it anywhere).

Oh wow- there’s a use for doing that! That’s sick! And do you have to go up slowly to get yourself used to the pressure change?

Good question! When you scuba dive you do go up slowly to prevent bubbles of nitrogen building up in your blood, but when you free dive there’s no need because the only air you have is a lung-full from when you inhaled at the surface. When you think about it, that volume of air can only decrease at lower pressures and when you decrease the pressure by ascending, the volume increases to only the original lung capacity as before so there’s no risk. Hoping that physical explanation makes sense, we’re in a NatSci thread after all!

Yes the second explanation does make sense! Why is it though that the nitrogen gets into your blood if you go too quickly up when you’re scuba diving?
