The paper with the ice cubes and sea water density.

How did you find it? I thought the paper was quite nasty and anticipate lower grade boundaries than last year.
was it the one where there was the ramp PAG and the physical and chemical change question.

If so, you are wronged, the exam was insane for how easy it was and the grade bounaries will be much higher than last years.

No clue about any of what you mentioned: OCR 21st Century Physics B Higher https://www.ocr.org.uk/qualification...259-from-2016/

One of the questions was one on clowns dropping water balloons on another's head.
Another was a graphical representation of alpha decay.

I got 115,900 because I rounded the current to 0.28. Will I lose marks?

I did it the hard way by calculating the charge by using the current and then calculating the energy using the charge and voltage

It was so hard. Soooooo hard. Right? Or was that just me? But I was proud of myself when I got the last question. The speed of the balloon one.
