Just wondering, how will answering these questions help me? (apart from learning new things, that is.) Is there any prize or scholarship or something?


Boosts self-esteem :yep:

But it's supposedly helps you prep up for the Lower Sixth Competition (the paper in June)

Yeah, I seem to be getting absolutely nowhere with silver either ._. any help would be appreciated too??


Silver is the Big Bang thing right? Chances are that you've seen the name of the process a fair couple of times by now- note how many He atoms there are and remember to add up the values from all the separate reactions.
Can anyone pm me with some help for Gold? I've tried every carboxylic/fatty acid I can think of, and I'm completely stumped.
Can you start this any time in the year as long as you finish by the end of Year 12?

The monthly challenge?

The monthly challenge is open to everyone so anyone can do the challenge. Its works where it changes per month but the challenge is open to everyone

In regards to the Lower Sixth Competition (the paper in June) I believe that's only available to Year 12 students
I think there were trophies which are awarded to students who stood first in their respective countries. Has there been any change in that? :confused:
