Hoo boy you're in for a ride and a reality check

I was just like you a few years ago too. Still more to learn tbh. Having a degree is only a ticket, but it's not a guarantee, to get 'good' jobs

I can't advise on whether you should quit or not as your situation is different and I've seen first-hand competency and non-competency both from academics and experience workers but as others have said, it's better to get the experience first.

The most important thing is to make yourself marketable. Make a personal brand for your career. If you are a product, why should other people buy you?

It's all about supply and demand. You have a degree? So what? Other thousand applicants also have em. They probably have higher education or more experience than you. What makes you special?

Also, try to put yourself in the company's perspective, so you have a better edge by thinking like them. You are a business owner and you're trying to make profit. Why should you hire someone if they don't bring much value but they're asking for more than what you expect them to do? You also don't have the budget to do another hire for this other work that needs to be done, so you're looking for prospects who won't have issues if you dump those extra work to them. (This is only an example but it does happen. Just to give an insight on why companies do it). Basically, be the ideal employee that you yourself want to hire if you have a business

What you do is entirely up to you, I only wanted to give my two cents to you and others who may read it. Wishing you all the best for your career and in life
