How did everyone find the exam?

I thought it seemed quite different to the other past papers... and really short for time!

For the triglyceride question, did you say it was HDL or LDL? I put LDLs and talked about how they increased blood cholesterol but I really wasn't sure

State a pre-natal test that could be carried out 11 weeks into pregnancy and then it asked to explain why the mother might choose not to have the pre-natal test

I talked about both cause they didn't really specify what type of lipoprotein was formed

Same, I didnt even understand the last few questions about the baby and the heart defect, made up some biology there lol
It was a saturated triglyceride (no double bonds). Therefore increased both HDL and LDL levels, however increased LDL levels by greater amount.

It was D which was the largest value something like 45690, there should be equal amounts of C and G so equal amounts of A and T.
