incoming arki student. any tips?

I'm an income arki student and may questions po ako:

1. Does school really matter?
2. What to do po while student pa lang so that mas tumaas ang sahod after college? kasi alam ko pong super liit lang usually ng sahod nang archi
3. Do i need to join orgs?
4. Do i need to join competitions?
5. What skill do i need to practice while student pa lang? 6.What advice po ang mabibigay mo saakin while and after studying bs archi?
