AS Biology A GRADE?!?

Remember that the ISA doesn't account for as many marks as your unit 1 and 2. But not having a good ISA grade makes getting an A that bit harder. It's definitely possible, just make sure you do all your revision!

Biology? AQA?

I'd just like to say one word and that is:

Shrew

(No matter how much you revise it is unlikely that they will test you on it and instead ask you two draw a bubble graphs or something to do with spearmans rank that will make you drop down a grade or two).

Ah, A level biology

yeaah true it'll just bring my exam scores down unless i score exceptionally well:\
any tips on AQA biology exam? its really applied biology

Not as AS- at AS a few more of the marks are on recall. So know your stuff confidently so you can a) regurgitate it and b) apply it. Get lots of sleep the night before the exam because the questions can be annoyingly worded and it takes energy to figure things out. Take a highlighter into the exam and highlight key words in the question- make sure you answer the question!

Master exam technique:

-> remember that correlation doesn't imply causation, try to think of an alternative cause and point out anomalies in the data or say that the independent factor needs to be isolated and tested against the dependent factor.

-> When answering a question, use the numbers in the data given to you.

-> One mark = one point generally.

-> Don't ramble on too much- this can put the examiner off and you can end up contradicting yourself.

-> Learn your key words.

-> With haemoglobin questions the answer should generally be like this: if the question says something about an animal that lives high up a mountain or at the bottom of the sea compared to one that lives at groundlevel make these points:

o There is less oxygen at the top of a mountain/bottom of sea/in the womb etc.
o Therefore the oxygen dissociation curve is shifted to the left (left = load (as in loads oxygen more easily) and right = reduced (as in reduced affinity for oxygen), meaning haemoglobin has greater affinity for oxygen.
o Meaning animal x can pick up more oxygen than animal y at a lower partial pressure of oxygen.

-> Remember there's a difference between explain and desribe- describe just means tell the examiner what the data shows, explain it means... well, that you need to explain it.

-> Sometimes the answer seems so simple that it can't be the answer- but go with your instincts.

thanks!! hopefully theres still time to get this A in the bag!
