Well in our school's eco version, we all have $10k, $5k had to be invested in two different currencies minimum and the other half had to be invested on shares in ASX.
That was pretty much it. We had a one hour window every week in class to write down our amendments.
In the end the people who won were those who had been watching the shares of different companies for a long time.
I went in going for companies that had a minimal decline and were starting to increase again. It worked well for most, except one company just kept crashing for some reason.
I think this went on for two months. In the end I lost like $30 out of the $10k and iirc some person lost about $700 and another gained about $500 (winners).
