How much further? lol
AMC requires effort too ;)

AMC requires effort?????? well I give it credit in some beautiful questions that have been produced by it :)

Further meaning whatever comes after it?? I don't know what this is. I assume more testing. Then more. Then more.

I've only been able to participate in it a few times due to my knack to not turn up to school for a few weeks at random intervals of the year. In those times i have done it, I'm sorry, but haven't. From the most recent past papers however, with the knowledge I now have, *some* of the questions are laughable.
