My GCSEs

I currently have 2 As in core science and additional science. The GCSEs I will get this year are in the following subjects: further additional science, maths, English language, English literature, ICT, geography, ancient history, health and social care, German and product design. I have a target of an A* in all of them excluding German which is an A. However, my exams haven't gone that well at all really and I'm not just saying that because I've looked at unofficial mark schemes and checked and it's not looking the best so I'm worried I'm going to be really disappointed on results day. I still have 6 exams left I'm worried I'm only going to get 4 A*s (if I'm really lucky and at a push), then 3As and 3Bs which might sound good to some people but it's not what I want. Everyone has their own different ideas of what they want and I just wouldn't be all that happy with those grades to be honest. It's not going to affect college or anything but I'm just going to be disappointed and regret not putting in more hard work or not concentrating better or focusing as much in exams and what not. Any advice or tips or anything?
