Well we are nearly there….. 24 hours to go until the main IGCSE Biology exam (worth 120 of the total 180 marks). I hope you are all excited and looking forward with optimism to being able to show the examiner how much you understand from the extensive specification. What should you be doing in this final 24 hours?
The most important thing is that you all get a good night’s sleep tonight. Please do not stay up late cramming -it does not work! The evidence base for this is completely clear: you will perform better tomorrow with a normal night’s sleep tonight. So please stop work an hour before you intend to go to bed, relax for an hour watching TV or socialising and then go to bed……
This afternoon you should want to look over a paper or two to familiarise yourself with the kinds of questions and the mark schemes. I would have a final look again at the summer 2015 and summer 2016 paper 1B scripts. Look at your answers and the kind of ways you lost marks. In particular focus on the longer answer questions (for 4,5 or 6 marks) and look at the mark schemes. Often there are marks available for saying obvious things but only if the correct vocabulary is used correctly.
Remember the PMG list of banned words:
Amount (oh no, please don’t ever write this in an exam – think – do you mean mass/volume/concentration?)
Level (do not talk about the level of something, you always mean “concentration” and concentration is a noun that actually means something!)
Substance – what substance are you talking about? oxygen? glucose?
Gases – in questions on gas exchange or transport, please do not write about “gases” – say which gases you mean!
Nutrients – not really a banned word but one that needs very very careful use….. A nutrient is a food molecule, for example glucose, an amino acid or a lipid. Nutrients like these are transported dissolved in blood plasma in mammals but if asked about it, don’t use the word but actually state which molecule you are talking about. None of these nutrients are absorbed into the roots of a plant. Plants absorb mineral ions (nitrate, phosphate, magnesium, potassium etc) through their roots into root hair cells by active transport.
Look over your revision notes a few final times to familiarise yourself with the key words. Focus your final revision on the key areas that you know will definitely come up: there will be a genetics question, there will be an experimental design question, the chances are that fish farming and fermenters will be there as usual……..
If you have worked hard for several weeks (and I know many of you have) you have little to fear in the exam from a lack of knowledge. The thing to fear is losing marks due to rushing, due to not reading the question and due to not giving yourself time to think. None of you will be rushed for time I promise, so please
- read every word in every question
- give yourself time to think before answering – even easy marks can be lost by rushing!
- plan longer answer questions to make sure you cover all the key points using the correct jargon – think before you write anything, “what are the key terms in this topic?” – and then make sure you use them correctly in your answer
Good luck! By the end of tomorrow you will have completed two thirds of your GCSE exams in Biology and that should be a happy thought……
