I did the same, my family also has a history of high cholesterol, so I went and got checked out by my GP beforehand (also making use of my taxes as I hardly ever go either). Reading was a bit on the high side, but not too bad so I bought those Flora Cholesterol lowering drinks and had 1 a day for 2 weeks before the class 1.
When they tested it for the class 1, it was normal.
