I have a cholesterol question..?

Alright, I had a blood test two weeks ago for a medicine I am on and the doctor said my cholesterol is a little high (it is at 171). I was wondering where I can get a chart to see what an ideal cholesterol is for my age.. I’m 17 years old, 6’1", and 220lbs, and male, if it matters. If anyone can provide a chart or give me an ideal rating, it would be much appreciated..
