Really good quiz however for question 34 it says there is only one disadvantage of a kidney transplant but this is not true! The disadvantages are:

  • The kidney may be rejected / need to take drugs to prevent this for the rest of your life.
  • Susceptible to other infections
  • Hazards of operation / anaesthetic
  • Shortage of matching donors
  • High initial cost

But other than this it is great! Thanks!

thank you, and yeah there are way more disadvantages but I was only able to give you one right answer and typing all of those disadvantages would have been a very long answer indeed. Perhaps I could have put one of these is one of the disadvantages of a kidney transplant, which one is it? Thank you for the feedback, I shall bear it in mind.

And I'm glad you liked the quiz :)

Just a couple of pointers...

Question 49 - amylase is a carbohydrase so surely both answers are correct?

Question 61 - glucose is a carbohydrate so surely both answers are correct?

Other than, fantastic. I shall have a look at the couple I got wrong :)

Yes amylase and carbohydrase could both be correct but following on from previous mark schemes the examiners always prefer carbohydrase and amylase in one of the "accept if the candidate has put amylase" sort of things. And yes glucose is a product of starch which is a carbohydrate but once again I tailored this quiz around what the exam mark schemes have been telling me and I'm sure that they want you to put carbohydrates as this involves glucose and all the other minerals needed by the micro-organisms.

Thank you for your feedback anyway :D

thanks again everyone! Good luck for all of your exams, I'm sure you will all do really well :)
