Everyone's getting so desperate about their lives now. their prelims, their A-levels, their universities, which to go to, bad common test results, et al. And i think we really have to put things into perspective. Yes, doing A-levels well is paramount in your education life: if you don't do it well, you've finished your education berfore uni on a low, and you might just miss out on a ticket to the train of success--a good university, and so on. However, yeah we can study and al that, but really please don't confuse your studying life with your actual life: you are more than your grades make you out to be. you've got a way-long life out ahead. you'll get married, get some pretty little kids, earn some bucks, drink some at a pub, listen to some music, get some love, hang out with friends, die, go to Heaven, if you believe in God, that is, and eternal life and so on....really there is no need to get all worried and desperate. yes, the time is short, but systematic revision should clear the little holes here and there?
