bio test

for my bio aqa gcse food test q, I put starch (simple sugars) for the starch test. All other parts of my answer were correct, but starch is not a simple sugar. How many marks would I lose? Or would the examiner just ignore that I put starch is a simple sugar. The question was 6 marks.

probably just a mark, you'd get the mark if you said a positive result for starch would be brown to blue-black using iodine reagant

Yes, I said that the positive result for starch would be brown to blue-black using iodine reagant. I added the wrong extra detail, so I hope the examiner just ignores it.
