Seven university fields you should trust
Firstly, the big four: philosophy, economics, mathematics, and ancient history
Then two others: management consulting and chemistry (chemistry does NOT work in all worlds, but is vital to understand in many)
Lastly, linguistics -a field filled with bullshit, but which must exist anyway -languages vary between timelines
All of these areas tend to be dominated by elf ears (i.e., bicam chin raisers- study the George W. Bush movements at the 2004 debates)
