It doesn't really matter how many GCSEs you get as long as you are able to acheive the next 'level' of education which is AS Levels.
Employers only take your best 8 or 9 GCSEs no matter what anyways so if for example somebody got:
9 A* 1 C and 2 D's it would be the same as a person who got 9 A* in theory.
I'm not sure about universities but i think GCSEs play a very minimal part in the thinking behind whether you get accepted into a University/Job or not, if any part at all. All they are generally bothered about is if you have passed English and Maths. A lot can be learnt from Year 11 to University, both socially and mentally.
For example, you could have just messed about in high school and scraped 5 GCSE's but then really got your act together and knuckled down and come away from college with good A-Level results.
Oh, and for the record, i did 11 GCSEs. 5 A*'s, 4 A's and 2 B's.
