Goldman Sachs Test

Hi

My friend did a Sachs IB summer internship in NYC this summer. This is what he said:
"Ive been chosen to put together a team for a high volatility trading competition. It's a paid 4 week internship during Christmas with 4 teams from the American Big 4"

He asked if I was interest and ofc I said yes but there's a test to make sure he isn't just picking anyone.

"The test should take two hours. One hour academic based on economics common trading strategies and interpreting company stats and then the usual numerical reasoning test. One hour trading simulation where you're limited to two fictional companied in 5 market sectors, two bond markets, two currency market and two commodities. You'll get news and you create a trading strategy. The first ones more important coz it's a Sachs pre requisite to get a certain percentage (70-75), the second won't really affect ur result but it will be forwarded to me and Sachs."

I've been self teaching myself Econ from Khan Academy, done micro and macro and several of the finance and capital markets playlists. This was mainly to get good A-level Econ knowledge as a foundation but only 1 video on Hedge Funds had about investment strategies (Long-short).
Does anyone have experience of the Sachs test, or direct me to resources I can learn about investment strategies?

Any books? Websites? He also said people were a very good source so I get varied viewpoints to have a varied portfolio, but I don't really know any IB'ers...

Thanks for any help.
