Should I change engineering major?

So I’m a second semester senior in highschool and I want to know if an engineer major at Cal Poly Pomona will be as difficult as it’s made out to be. Im only asking this because my last math course i took was pre calc. Would the math courses be too difficult for me because considering how much i have to pay yearly i dont want to drop out and waste my parents money.

How would you think strangers on this site could possibly determine whether or not you have the aptitude to succeed in engineering?

Yes you would need to take upper level math classes.

Nobody wants to drop out or waste money regardless of how much tuition costs.
