Getting through school is pretty tough - who doesn't shudder at memories of raging hormones, first kisses and algebra?
Some kids just don't seem to get it as bad as the rest of us though. Call it star quality, the X Factor or the uncanny ability to ALWAYS land the lead role in the school play, some kids get all the luck.
And sometimes, just sometimes, those kids turn into mega celebrities.
If you didn't break into the big leagues - don't worry. Here are just some celebrity former pupils for Glasgow schools to boast about ...
Who knows? You might discover that a celebrity went to the same school as you - or maybe you remember them well from when they were snotty of nose and skint of knee.
