Before we start, I want to touch on something very important: your grades. You may be thinking that because you're in college now, your grades don't matter and everyone will hire you because you have a college degree. Unfortunately, this couldn't be further from the truth. Your grades matter now more than ever.
And the reason for this is simple: the best companies and grad school programs need to set GPA thresholds; otherwise, they'd be flooded by too many applicants. They focus on the GPA because as a student, you have virtually no work experience, and your GPA is the most significant factor on your resume. It is much more than a number; it's a signal that you're smart, but also that you're willing to work hard, and that's who companies want to invest in and hire.
So unless you're above the company's GPA threshold, which is 3.6 for a lot of companies, you'll not even be able to get your foot in the door and get an interview. Beware of people who say that your GPA is not important. This may be true once you're a few years into your professional career, but it is super important for your summer internships and first jobs. And the thing is, your career steps are determined by your previous jobs. For example, if your first job pays $75K and your friend's first job pays them $45K, your second job will pay higher than your friend's second job. And it may be hard for your friend to ever catch up.
Your best opportunities will always be at the top. So my advice to you is this: don't shut the door on your future before you even start and get the highest possible GPA in the toughest major you can. This is not to say that it's all about money, but your education costs a fortune and a lot of your time. So make the most of it and give yourself the option to lead a comfortable high-income life. If you want it, that's fine; if you don't want it, that's fine too, but it's much worse when you don't have the option to choose and you are forced into a low-income life that's hard for you and everyone around you.
And it's not just about chasing the grades either. Learning is amazing. You have the chance to expand your mind, learn something new and difficult, and become a better, smarter person than you are now. So do yourself a favor and don't let this opportunity go to waste.
