im confident that is the method but im pretty sure i said 3A = ... which was a blue on my part.

you just had to use the ratio they gave you. it ended up... A/3 = Ae^(-kt) so divide through by A 1/3 = e^(-kt) t = ln(1/3) / -k i think i used 3A in my haste but thats how you do it...

As im only doing it now with you i cant really comment on its effectiveness but ill throw my method out there anyway.. i just get the syllabus and distinguish it by colour in word, then i dig out all my notes and gradually go through it summarising to the required information in a different...
