! WARNING NOT ADVICE !
I literally stopped caring about my grades. I'm a college student and my career path requires that I have a degree in my major (or related field) and originally I was going to transfer to another school to major in a more specific major that would help me be better prepared for field work.
What ended up happening was I could never reach the gpa I needed to transfer so I gave up on transfering. Then at a lower gpa I could switch my major to a slightly better major but guess what? Same thing happened.
At that point I thought "My career already accepts my major why am I trying to change it?" Then I went even further and stopped caring about my grades. As long as I pass the class I will still get my degree and no employers care about your gpa in college so why should I? I made up my mind and said fuck it to stress! (even though I still definitely have stress)
Welcome to my sad failure of a life in school.
On the other hand my career is going great. I have a job in my field which is giving me far more experience than school ever would. It took 2 years of persistence to get this job but I got it and I love it.
You've probably heard this a million times but you just need to do it. Get rid of any distractions and just focus on whatever subject it is you need to study for. If you need to take a break every 10 minutes then so be it. You just need to sit down and get through all the material you need to in order to pass your exam. Read whatever textbook you have, write notes, watch youtube videos; as long as you think it will help you learn and get ready. If it's a subject like math or physics then do a ton of practice questions until you 100%understand how to solve a problem. If its something like biology then you should definitelt try pracrice questions too, but textbooks dont really have answer keys for a lot of those questions (at least in my experience). One thing that worked for me was that I'd read the material and then try to reiterate it as if I was answering a question on a test. Basically you just want to be able to repeat what youre trying to learn in your own words. Feel free to message me if you have any questions or want some more tips!
TLDR; You just need to go for it, studying sucks but you have to just force yourself sometimes. Do a ton of practice questions until youre able to answer them without help/references
Please study just a little bit. I don't think it's a good idea to go "fuck school" but you also shouldn't stress yourself out. Personally, I have a short attention span towards things I'm not interested in. I'll be very focused for about half an hour but then give up. If you're similar to me, I'd say burn up that short little span of time where you can really be focused, take a break to completely clear your mind of the subject and then repeat. It doesn't work great but it's the best I can give you.
Here how i usally do it if you lack in quality then improve your quantity to made it up meaning start studying long before the exam so even if we sucks at memorizing or calculations we still have many hours to practice and improve. Also with many hours to spare we can try other studying methods since sometimes its not that we are dumb or hopeless we just havent found the best way to study yet that suit us the most.

i have huge exams coming up that can determine my future but i suck at studying and hate how half my life is based on grades
