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.
