You know what your compensation is going to be when you get the job offer. You agree to that offer, then 2 months later you say "oh I contributed a lot so you need to pay me more"? Why do you feel like if you do more they have to pay you more? You agreed to give an employer 40 hours of your time to perform the responsibilities the job requires in exchange for an agreed upon, fixed amount of money. That's what the agreement between you and the employer is. If you have other expectations, you should negotiate them before accepting the offer. Don't like the offer? Don't accept it. Once you accept it though, stick to your word, don't change the terms 2 months in because you feel like it. Corporations just don't think the way you seem to - you don't get rewarded for A+ grades. You get the same paycheck. That's the default for most people at your level. Don't set yourself up for failure by going into a job thinking you'll do more and get more money. You won't at first, and definitely not within 2 months. Maybe after 2 years as a promotion, but that means you have to work at the same company in the same position for 2+ years.
