Well done I scraped an A in bio, and French and Physics were full UMS I think
Is chem ocr a?
Wow, well done!
We haven't got the actual marks for Mechanics/Physics yet Got 97% on the C1/C2 paper though which I was happy with, doubt I did anywhere as good as that on Mechanics or Physics though

ahhh so like Cl is both oxidised and reduced as it changes from 0 to -1 oxidation state in HCl and changes from 0 to +7 oxidation state in compound x (couldn't remember name )

No!!! That gets 1/3 still!!
You'd have to say:
Reaction is a disproportionation reaction because Cl is both oxidized (0 to +7) and reduced (0 to -1) simultaneously.
Ngggggghhhhhhh, I made so many stupid mistakes in my chemistry test today! But on the bright side there was a long question on iodine-thiosulfate titrations, which I think I did okay on *fingers crossed*
