<human>: Can you give me a shortened version of the text?

I'm a 21 year old Junior in my college, and yet I only have the credits of a freshman. I'm an engineering major and calculus is is not my strong suit. This is my third semester taking it and while third time's the charm because  I'm doing really well now. But I feel horrible I feel like I'm wasting my time needing to retake this class again. I see you freshmen and sophomores surpassing me and I just feel so bad and it makes me want to quit because I know I'm going to need to take more than 4 or even 5 years just to get an engineering degree. I feel like people judge me for taking that much longer that I'm stupid or something. All of my other classmates that are now Juniors and seniors are getting internships or even jobs that pay more than 8 bucks an hour and I just feel like I'm left behind here like I'm stuck and not going anywhere
<bot>: 21 years old taking freshman classes i feel like I'm just watching other people continue onto professional lives and I feel stupid because of it, it makes me want to give up
