I have created a group for IGCSE Biology students on Quizlet and you are welcome to join using the link above. There are some topics already there in this group and I hope to add more material over the coming weeks. Please join and I hope you find it useful.
Most of the sets are modified from other users but I have been through and edited them, to make them ideal for A* learning.
Please remember the content is designed for Single Subject Biology so Dual Award students will need to be selective in your use of the materials. But I hope you enjoy!
Sometimes the hardest thing with revision is getting started….. This post is meant to help you think about how best to make the most difficult first steps towards securing your A* grade. I went through this with my Y11 classes before the end of term so this is just a re-cap. There are very few original thoughts here (story of my life….) but perhaps I can inspire you to get started early in the holidays with your Biology revision….?
Most important – have a plan for the Easter holidays
Work out how many days you have available to revise over the holidays. This will not be the same as the total number of days of holiday as you should have rest days where you do no work at all. Ask your parents what family commitments you have coming up, think about your social life and subtract the days when it will be impossible for you to work. This gives you a number of “working days”.
What do you do on a “working day”?
I suggest that you never try to do more than 4-5 hours of work in any one day. Revision is not measured in hours, it is measured in progress and learning. 2 hours of effective work might be better than 10 hours inefficient time at your desk. The aim here is to maximise the benefit you gain from your revision, not simply clocking up the hours.
Here is how I would organise things if it were me….. Divide the working day into three sessions:
- Morning: 9.30am – 12pm
- Afternoon: 2pm – 4.30pm
- Evening: 7pm – 9.30pm
The plan is this. On a working day you always work in the morning session, every day, no excuses…. Ask your parents to be ruthless in waking you up and don’t allow yourself ever to sleep later than 8.30am or so. There will be plenty of time for lie-ins and getting up at lunchtime in the summer holidays. By midday, you will always have done half the work of the day. How happy will that make you feel? Then choose either the afternoon or evening session (but never both) depending on how you feel and what other plans you have for the day.
How to organise a “revision session”
You need a kitchen timer like the one shown above (not to scale as the textbook is quite large and the timer is quite small…..). I bet if you ask nicely your mum or dad will let you borrow the one in the kitchen. For Biology work, you also need your textbook and revision notes. This is how I suggest you work. Set the timer to 25 minutes, switch off your phone and start work. Work at a topic until the buzzer sounds – no distractions allowed…. If your phone beeps, ignore it. Snapchat can wait! After 25 minutes stop and have 5 minutes off. Make a cup of tea, check your phone and repeat.
I suggest that you revise 5 different subjects in one session. (5 x 25 minutes) You must try to make your revision interesting so you don’t get bored. Bored people do not learn anything……
Different people learn best in different ways so do what works for you. What works for no-one is just reading…. Make notes, revision cards, write out definitions of key facts, use IT if that rocks your boat, whatever you like just do not sit and read your textbook. The key thing is to go over ideas as many times as possible, test yourself on your recall of facts and then try to practise some past paper questions. Most importantly, try to have fun! If you are enjoying it, you will be learning and that is the idea I guess.
Finally, the main benefit of having a plan is this….. When you are not supposed to be working (according to your beautifully crafted plan), you can switch off properly without feeling even a teeny bit guilty. You can combine revising with getting on with enjoying your life. The two things are not mutually exclusive!! And with luck you will avoid feeling like Stewie in the picture below. If only he had a proper revision plan…..
I hope the trial paper this morning for D block went well. I am marking my two divisions’ scripts later this week and will put some generic feedback on this site when I get a chance…. Good luck with all your other papers.
If you are revising for E Michaelmas trials next week, I suggest you go through this checklist and make sure you understand each point fully….. This list could be the basis for making some revision notes.
- Understand the differences between atoms and molecules
- What is a polymer? Give some biological examples of polymers and describe their structure.
- What are the chemical tests for glucose and starch?
- How do enzymes work as catalysts?
- Draw a graph to show how temperature effects the rate of an enzyme-catalysed reaction. Annotate the graph to explain why this pattern is observed.
- Now do the same but for the effect of pH on enzyme reactions…..
- Write down the word and balanced chemical equations for photosynthesis.
- Why is photosynthesis such an important process in the plant (and in the ecosystem)?
- Draw an annotated diagram to show the structure of a leaf and how it is adapted for photosynthesis.
- How do you test a leaf for starch? How do you measure rates of photosynthesis using an aquatic plant? What variables could you alter in this set up?
- Explain differences in function between xylem and phloem.
- How is water absorbed in root hair cells? Explain osmosis (good luck!)
- What are the differences between diffusion and active transport? Give two biological examples of each.
- What is transpiration? How can you measure it?
- What factors affect rates of transpiration in a plant?
- What is the difference between a pesticide and a fertiliser?
- What are the advantages and disadvantages of chemical pesticides and biological control of pests?
Many of the students I teach are facing end-of-term exams next week. And for my Y9 and Y10 students these are multiple choice papers which pose a different challenge to the more usual structured answer format. So here is a quick PMG guide to help you score the highest mark you can on this kind of paper. Good luck!
1) Don’t underestimate the opposition!
The biggest mistake students make with these exams is to be over-confident. The reason GCSE exams no longer contain any multiple choice questions is because it was felt that this type of question is too difficult. The examiner, by selecting four incorrect responses to every question, is trying to catch you out and the more plausible the incorrect responses, the better the question! So your understanding needs to be really good to not be tricky by these underhand tactics…. Get revising!
2) Read the question carefully.
This skill is tested even more fully in a multiple choice exam. You spend less time writing answers (obviously), so this allows more time for reading and thinking. Even with a “mark a minute” time frame, there is time for thinking and planning before deciding on a correct answer. Write on the question paper, use it for rough work and planning. And RTQ carefully – with many similar but incorrect answers on the page, it is so easy to decide too quickly what the correct response is and so miss out on marks you could obtain with a little more care.
3) Try to eliminate the obviously incorrect answers: this will mean you are only focussing your thinking on the possibles. It also means if you have to guess, you are maximising your odds of being lucky! But be careful….. This strategy has an obvious flaw so be careful in what you eliminate.
4) Your best chance of getting a question right is the first time you answer it. So I suggest you leave blank any answers you are unsure of on your first go through the paper. Don’t spend more than a minute on any question on this first pass through the paper. You can come back to look at the harder questions at the end of the exam. It is much harder in an exam to spot an error in a question you have already answered, so I would leave answers blank unless I am sure I am right….
5) Keep an eye on the time. After 20 minutes of the exam, check that you are ahead of the time. Most multiple choice exams are a “mark a minute” but I know that in our internal exams this isn’t always the case, so check.
6) Finally, make sure you answer every question. There is only positive marking in these exams so you should always guess (see point 3 above). The only way you can guarantee you won’t get a mark is if you leave the question blank!
Take a pencil and a rubber to these exams – both will be useful! And good luck……..
Clearly there is a lot of last minute cramming going on before IGCSE Biology paper 2 tomorrow….
That is absolutely fine but please remember you also need a good night’s sleep so your head is clear. Knowledge is only a part of the skills required tomorrow in the exam and at least as big a part will be played by your ability to read the question, to think clearly, to recall good answers and to show your understanding clearly on the page. All of these will benefit if you get a good night’s sleep tonight!
Take your time to read the question carefully and before you start writing any response, take a moment to think “what are the key scientific terms I need to use to show my understanding?” So many marks are lost by waffling on without actually stating the key idea!
May 16th was the busiest day on this blog. I wonder if we can beat it before paper 2 comes up after half term……
I will try to put up a few more posts on the remaining topics so keep checking….. And keep working hard! 25 minute bursts of focused, intensive revision is best.
I am always very wary of trying to “second guess” IGCSE examiners and predict what questions might come up as it can be a risky business. But as all the Y11 students out there start a well-earned half term, I thought I would put up a short post with some suggestions as to areas of the specification that have not yet been tested.
Important Disclaimer: Remember that the examiners can set questions on the entire specification in paper 2 (including all the bullet points in bold). It seems more likely to me that the questions will be on areas of the specification not yet tested in paper 1 but you cannot guarantee it. So please make sure you revise the entire specification and are as prepared as you can for any questions that might come up.

Finally, keep working hard. It is easy to get too comfortable about your exams now that many have already been sat. A little bit of fear is still a good thing, so remember that 33% of your GCSE marks are still up for grabs and this paper 2 will make all the difference in determining your final grade. No short cuts now, keep being organised, methodical and diligent. The summer holiday will give you plenty of opportunities to socialise, have fun and relax so try to keep the momentum up in this coming week. Good luck!
