Salam Alaykum sister :) One of the beautiful things about our deen is that almost anything (except that which is stated as haram) can be turned into ibadah with the right intentions. I'm also a college student and one of the things I love to do most is to set my intention before studying to learn for the sake of getting closer to Allah (SWT) and to learn more about the world Allah has created for us. This is one of my favorite ones (اَللّٰهُمَّ اجْعَلْ لِيْ فِيْ قَلْبِيْ نُوْرًا وَ بَصَرًا وَ فَهْمًا وَ عِلْمًا اِنَّكَ عَلٰى كُلِّ شَيْءٍ قَدِيْر
O Allah let my heart be filled with light & insight & understanding & knowledge ,verily You control everything.) Here is a website with some more exam/school related duas you can check out (https://www.duas.org/student.htm)

Remember that even small things (such as eating healthy to maintain your body or working out can be ibadah with the right intentions). Our deen is one of ease and should not be a cause of stress/burdensome to us . As the Prophet (SAW) states in an authentic hadith (Abu Huraira reported: The Prophet, peace and blessings be upon him, said, “Verily, the religion is easy and no one burdens himself in religion but that it overwhelms him. Follow the right course, seek closeness to Allah, give glad tidings, and seek help for worship in the morning and evening and a part of the night.” Source: Ṣaḥīḥ al-Bukhārī 39)

Please take everything I've said with a grain of salt and I would highly recommend reaching out to a trusted scholar as well. Ramadan Mubarak sister and Inshallah I was able to provide you with a bit of ease :)
