I wouldn't aim too high, because if you don't reach your goal, you'll be devastated. I'm not aiming for a specific mark; I'm just trying my absolute best. If you put in the effort, then there's nothing else you can do. But yeah, generally I'm aiming for about 96. I think aiming for 99.9 is just unrealistic for me; I think I'd go insane with all the studying. But I want to stay motivated, so I've put up motivational quotes above my desk. I think the most important thing in staying focused and motivated is breaking up massive tasks into small ones. It's the best for me, because I procrastinate a lot. Rewarding yourself is also important. Don't hammer yourself for not finishing a big task in a certain amount of time. Exercising and a healthy diet are really important; drink heaps of water and exercise every couple of days; it's so good for feeling refreshed, and helps me stay focused.
