Learning about financial world and models ?

Tittle might sound confusing so let me elaborate. I go to a top 10 business school where almost all the kids know a lot about finance already . Me on the other hand didn’t alway wanted to do finance and now during my sophomore year I really feel like I’m behind then others and should gain knowledge, in my school your major classes doesn’t start till junior year so I have a year till finance classes starts . Like I want to learn about how markets work , want to learn basics about financial models . Where do I learnt this stuff from? Any books? People say Wall Street journal but how exactly you gain that knowledge from wsj. Will really appreciate any advice .
