confused and scared lmao

Hello everyone, I'm a 4th year finance student at a non target university in a small city so either i make it big or live paycheck to paycheck. I'm writing this because I'm a bit confused about everything and i don't know what I'm supposed to do , i know that i didn't do my research properly when i decided to chose finance but there was so much going on and i needed to make a choice so i went for it , I'm enrolled in a program called programme grande ecole (very known program in France) and its a 5 year program , im set to graduate with a masters degree in 2026.  my question is where and how do i start ? are there certificates that i can try and get to help me with getting more knowledge or more sufficient skills? where can i learn more about the kind of jobs that i might be working ? where can i find opportunities, internships or programs that i cam apply for ? is networking really the base to getting a job in finance ? where do i look for info ? 

ill appreciate whatever info you might share even if you think its unimportant or small

thank you again and have a great day
