Have you tried to identify your own personal peaks and troughs cycle? By that, I mean have you identified your best time to study. For instance, you may find that you peak early morning, say at 9am, and you might be able to take in more information and retain it for longer at that time.(a peak) But by 11.15 you might be slowing down and you cant take as much in as you could at 9am. (a trough). You will also need regular breaks. Experts tell us that we should only really study for periods of 45 minutes at a time, then have a break for about 10 - 15minutes, and when you have a break move away from your desk - go somewhere else like into another room for a few minutes. Also, you dont say how often you are studying, but if it is everyday then that can be detrimental. Sometimes you need to take a day or so off from studying as you could easily burn out. It is difficult having to learn something that you really aren't that interested in, the only advise I can give you is to just grit your teeth and persevere. Just keep thinking 'It'll all be over soon'

Why are you studying? Take a good, hard look. Chances are that the logic goes something like this... "if I don't study, I won't pass my classes. If I don't pass my classes, I won't graduate and get a degree / diploma, and then I'll end up with a miserable job or no job at all and suffer the rest of my life". So studying is this roundabout way of preventing a miserable life in the future. Are you inspired by that? I'm guessing "no". To be satisfying, it really helps if your daily activities are "integrated" with your goals and values. Studying can be stepping along the way to a future you're really enthusiastic about, or it can be drudgery performed because you believe you "have to do it". I say give yourself permission to quit. Why bother? If studying doesn't fulfill something worthwhile for you, if it doesn't connect up with who you are and what you want to do with your life, then what is your life about, and why go through all that suffering? Chances are, if you answer the "big questions" about who you are and what you want to accomplish in life, you'll have a better relationship with school -- you'll either stop studying what doesn't matter, or you'll be able to come at it with a perspective that allows it to "fit" with your vision for the future. But either way, I recommend you stop suffering about it.
