Someone mentioned earlier in the thread that employers only really care about how many GCSE's you have rather than the exact grades. This is completely true, and in some cases employers only really care about whether you have your English and your Maths. Of course you should set your sites high, but once you go on to do you’re A levels, and maybe a degree, your GCSE's are completely overlooked. Once you get you’re A levels, standard CV's do not require that you list your grades for your GCSE's, but require that you say how many you have. It is only at A level that the CV's require you to list your grades, and for your degree every subject should be listed with the percentage attained. The higher your qualification, the more details the employer wants to see. If you are moving on the higher education, GCSE's can be seen as an entry point, and you will already know what you want to achieve. It is only when you enter college that you should really start working hard, especially if you have plans to go to universities. Remember, A levels get you into university and not GCSE’s. It is only the great universities that will look at your whole academic picture.
