okay physics: 6 marker on big bang (cmbr and red shift) another 6 marker on how radio waves and gamma rays are produced. a TON of maths- rearranging and graphs. half life question was 17100

is this triple science?

yes

yes you are correct also on electroplating 2 marker of the advnatges and isotopes also. Do you know what comes up on the physical and biology? also by any chance do you know the ocr exonomics

what isotopes one

there was a page about protiens and it was a graph, also there was something about heart disease go over that there was this question and it was to design a plan of measuring reaction time. yhh i though that question was weird.

do you remember any multiple choices so that i can be sure not to flop those at least lol
