i think you are able to do around 11 GSCE that will be average but you can also do more than this it depends on the person. Some people even do a19 or 20 GCSE but you must be able to pass them.

YOU NEED GCSEs
You can try the Citizens Advice Bureau in Britain. They should be able to help you.
It depends entirely on what you want to study.

None. All you need is talent :)
7-8 is average, some schools will go in for up to 10. Usually kids with insanely high numbers of GCSEs do them out of school, or do them early. In some cases they speak a foreign language at home, so its easy for them. I wouldn't worry too much about the number of GCSEs you take, just make sure that you get good grades. Universities look to make offers based off your A levels anyway. For more information see How many GCSEs link.
