Amazing! Thank you! I feel really confident with these now, I'm off to try a past paper question that I couldn't do yesterday but I will definitely be able to do now!

you started off incorrectly
your meant to do
q(proportionality sign)1/t squared
then you would do q=k/t squared

dont take this as an insult its just a correction
