Senior in high school, deciding what to study. Any advice welcomed. Thank you!

Hello, right now I am senior in high school and deciding what to study. Luckily, I am admitted to all of the universities I was/am deciding between. Basically, I do not know what I want to do exactly (in finance), and I also feel that I am not as informed about the potential jobs as I would like to (yes, I have read descriptions and watched videos about various jobs in finance, but I still think I do not know much about them) so the decision is little bit harder for me. I also think I have wide spectrum of activities related to these jobs which I enjoy doing, for example:

• playing with options (short-term investing): the rush, the speed, the need of fast decision making, also the “chill” when markets are closed

• long-term investing: doing thorough analysis of some company, working in a team to achieve something (I am in a university group of investors (got there through my friend), in analyst team → creating documents/presentations of potential investment opportunities)

• I have little Ebay business going, thinking about expanding this summer to my own website (so selling/buying (making deals), creating business strategy, taking care of accounting (rather duty than something I enjoy doing))

• working with computers/trying to get back to programming (I have little experience from high school (basics of programming with Delphi), participated with decent results in national cybernetics/cybersecurity competition, doing MIT course (Introduction to Computer Science and Programming Using Python, and thinking about Machine learning with Python for finance professionals)

• math

• poker

I am basically thinking about jobs from quant through trading to IB, but I think I would prefer something in between (not only based on math and programming or on the other hand on social skills).

So now the important part, the universities. I am living in central Europe and I was thinking about doing undergrad here and masters in western Europe/USA (if it will be possible), so I must not only decide on the degree itself but also the possibilities of the university to prepare me for studying abroad (language, networking, …)

I am deciding between:

1) Finance (more practically/soft oriented than 3), but possibility of better GPA and higher chance of getting to good university abroad (they are in some group of world renowned finance/economics universities)

2) Mathematical Methods in Economics (+specialization in Econometrics and Operational Research), (same university as 1), only different program)

3) Economics and Finance (more theoretically oriented than 1) → few best students each year transfer to Oxford/Cambridge)

4) Financial Mathematics

My questions is, which university would you recommend (perhaps taking into account keeping as many future career paths as possible). Thank you very much.

PS: sorry for the imperfect English, trying to work on that
