yeah i definetly found it the worst, i dont have a farming/particularly animal background and 'common sense' really dosent come into it. Remember its a lot easier to think something is 'easy' when you've 'been there done that' and passed, than when you are right there doing it!
also, if alot of you found it the same then take comfort in that. our year certainly did!(and do with every exam to date!)
yeah, learn the enzymes, get easy marks if you do!
