Hello, everybody. I am a high-school student about to finish school (in fact, I only have to pass examinations now). I am 17 years old. I have not been able to really grasp all concepts and have a good grip on Physics, Mathematics and Chemistry and have thus planned to take one year off for sure before I apply for admission in different universities. But, should the need arise - and it is very likely - that I take another year off, would it be a good choice that I may take without regret? I'd be 19 then, would that be too late to apply; or my knowledge too little for my age then? Can I get along fine without taking that extra year off? Did you take any time off? Thanks.
