I’m writing this on Friday evening and the 2018 IGCSE Biology paper 2 is on Monday. So you are almost there…..
What can you do in the final two days?
- Look over the topics that can only appear in paper 2 and make sure you understand them as well as you can.
- Look at my post with some guesses as to what topics were not assessed on paper 1 and make sure you understand them as well as you can.
- One last work through those topics in the specification where you know your knowledge or understanding is not great (don’t waste time this weekend going over things you definitely already understand!)
- Rest properly, get two proper nights’ sleep so you are relaxed and ready to THINK in the exam on Monday. You will need some downtime this weekend to enjoy yourself and switch off thinking about exams…..
Good luck to you all! Your study of GCSE Biology is almost over… I will have my fingers crossed that the exam paper on Monday allows you to demonstrate the detailed knowledge and understanding you have built up
I hope readers of my blog felt that the Biology paper 1B went well earlier this week. For what it is worth, I thought it was a good but challenging paper but there is nothing at all on there that seemed unfair to me. I am confident that it gave students a good chance to show the understanding and knowledge you have built up over three years. But….. you still have 33% of your marks still available to you, so my thoughts have now turned to paper 2B in a few weeks time.
I have been through the paper 1B carefully to look at which subject areas have been tested in the questions. This might allow you to focus your revision now onto topic areas that have not yet come up. But the next point is very important: there is absolutely nothing that says they cannot ask questions on the some of the same topics inboth papers. Predicting exam questions is a dangerous game (!?!) and there is absolutely nothing in this blog post that should contradict the idea that you need to be fully clued up and ready for questions on every single specification point when you sit your paper 2B.
But there are some things we know about what is likely to appear in the paper 2B.
- Firstly there are some specification points in bold that cannot be assessed in paper 1 and can only appear in paper 2. I have a blog post that lists these so I won’t type them all out again. Have a look here to see a full list of the bullet points in bold….
- Listed below are some topic areas that were not tested at all in the summer 2018 paper 1B. I would anticipate that several of these will definitely appear in paper 2B so if I were in your position, these would be my top priorities for revision in the coming weeks:
Variety of Living organisms and 5 Kingdom Classification 1.2
Movement of substances into and out of cells – Diffusion, Osmosis and Active Transport 2.12, 2.13, 2.14, 2.15, 2.16
Transport in Plants – Xylem and Phloem 2.51, 2.52, 2.53, 2.54, 2.55. 2.56
Heart Structure and Circulatory Systems 2.63, 2.64, 2.65, 2.66
Human Nervous Systems 2.83, 2.84, 2.85, 2.86,
The Eye 2.87, 2.88, 2.89,
Reproduction in Flowering Plants 3.3, 3.4, 3.5, 3.6, 3.7
Reproduction in Humans 3.8, 3.9, 3.10, 3.11, 3.12
DNA and Genetics – this must come up!! 3.13, 3.14, 3.15, 3.16, 3.17, 3.18, 3.19, 3.20, 3.21, 3.22
Ecology – Food chains and Webs, quadrats etc. 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7
Carbon and Nitrogen Cycles 4.8, 4.9, 4.10
Selective Breeding 5.10, 5.11
Genetic Modification 5.12, 5.13, 5.14, 5.15, 5.16
Cloning 5.17, 5.18, 5.19, 5.20
The focus of your revision now should be looking at past papers and mark schemes. I know many of you have done this already for paper 1B.
If you want more past papers and mark schemes, I suggest you download them for free from this website: http://www.physicsandmathstutor.com/past-papers/gcse-biology/edexcel-igcse-paper-2/
Please remember there are posts on my website for every single specification point above. Just type in the specification code in the search box and it should (?!) take you straight to the relevant page. Please do ask me questions or leave comments at the bottom of any posts. It may take a while for them to be visible as I have to “approve” them to remove spam. You would be amazed at some of the stuff I seem to attract from the depths of the internet…..
Keep working hard and good luck!
The post above was written a couple of years ago for my Y11 students embarking on Easter revision. I know that some of my current 5th formers are working this week so I thought I would re-post it. Some things have changed since 2015 (notably the sad demise of Zondle) but the key principles remain…. I hope it helps!
I wish you all the best of luck on results day. Be pleased (but not too pleased) if you’ve done better than you expected and don’t be too disappointed if the reverse is true. GCSE grades are important in determining the next stages of your education but do remember that in 5 years time, no-one will ever again be interested in your news from today….
I think the most important thing to think about today is this. From around the beginning of April until the end of your final GCSE exam, you have been working independently, working things out for yourself, making notes and using web resources to improve your learning and understanding. You have decided what to study and how best to achieve your learning goals. And these are exactly the skills that will be needed to make a success of the next stage of your education! So the question is “can you keep up these high levels of motivation/determination/organisation when you start your A level courses in September?”
But I hope you will find time for some celebrations before the serious stuff starts again in September! Enjoy the rest of your summer.
This post starts with a massive proviso of course. Making predictions as to which topics might appear in a future exam is a very risky business. The paper 2 you will all sit after half term can test material from the entire specification (including all the specification points in bold) and there is absolutely no guarantee that topics tested in paper 1 may not reappear in some form in paper 2.
So the proviso is this: the only way to be fully prepared for paper 2 is to revise the entire specification so that you are prepared for whatever the examiners might throw at you.
But having said that, it seems sensible to focus your revision for paper 2 onto topic areas that were not examined in paper 1. If I were in your position, these are the topic areas for which I would be doing most of my revision in the coming weeks:
- Respiration 2.33 – 2.37
- Gas exchange in Plants 2.38-2.43
- Transport in Plants 2.49 – 2.56
- Transport in Humans 2.57 – 2.66
- Kidney 2.68 – 2.76
- Reproduction 3.1 – 3.12
- Food Chains and Energy Flow 4.4 – 4.7
- Nitrogen and Water Cycles 4.8, 4.10
- Human Influences on Environment 4.11 – 4.17
- Food Production (including fish farming) 5.1 – 5.9
- Selective Breeding and Genetic Modification 5.10 – 5.16
The bad news is that this list above still forms a large proportion of the extensive EdExcel IGCSE Biology specification but the good news is that there are PMGBiology blog posts on all the above. So please use the search function on my homepage to find material to help you revise.
Practice papers and mark schemes are available online (and for my students on the school Firefly page)
Keep working hard – you are almost there and the summer to come will be long and restful….
For those students following the EdExcel IGCSE Biology course there are now just three days to go until the paper 1. This is the two hour exam covering all the specification (with the exception of the handful of content points in bold). If you started revision early enough, you should know be feeling confident that you have the knowledge and understanding needed for whatever challenge the examiner might throw at you. So how best to use your time in the final few days…? It is a tricky question as the answer will vary for different people – you must always do what you think is best for you and your chances.
But if it were me, I would be trying to do the following:
- Have a go at as many past paper questions as possible over the weekend. Answer the questions under exam conditions, then mark them yourselves using the mark schemes available online. Pay particular attention to marks lost due to poor reading/interpretation of the question or poor-exam technique.
- Prepare yourself for the questions that you “know” will come up on Tuesday. It is almost certain that there will be a genetics question to make sure you remember how to set out genetic crosses correctly. There is always a graph to plot and questions asking you to describe the pattern in a set of results. How can you ensure you always get full marks on these questions which require no biological understanding to answer?
- Look at the experimental design questions and continue to practise them. Check over all the required practicals mentioned in the specification and ensure you understand how they work.
Finally on Monday night, please get an early night so you are refreshed and ready for a 2 hour paper. There is no point doing hours and hours of last minute cramming as it simply doesn’t work. If the Biology exam were like a Spanish vocab test then I would encourage you to spend four hours before the paper going over and over the material….. But your exam is going to require you to interpret data, to make suggestions and come up with explanations for things you haven’t seen before. You cannot think clearly or concentrate fully on reading the question when you are exhausted. So if you decide to cram, the chances are that many more marks will be lost through tiredness than will be gained by any short-term memory gains.
Please go to bed at a normal time on Monday night and wake up at a normal time on Tuesday morning.
And the very best of luck to you all!
There are one or two words which you should never use in your answers to IGCSE Biology papers.
- The boys I teach know that amount is a banned word. If you find yourself writing amount, please cross it out immediately and think which of the following terms is actually the word you should be using: concentration, volume, mass, number .
[Amount has a specific meaning in science: it means the number of moles of a substance and seeing as you don’t need to know about the dreaded mole for Biology, it should never be used.]
(this is a good photo of the dreaded mole)
- Be wary of using the word nutrient without giving an example of what molecule you mean. A nutrient is food molecule like glucose, amino acid or lipid. When you are describing the things in soil that are absorbed into the roots and are transported in xylem, it is better to refer to them as minerals.
- Level does not mean the same as concentration. Don’t write about the level of oxygen when you mean concentration.
In Ancient Greece, the Doric order was one of their favoured architectural styles and offered the simplest way of decorating columns.. As you can see from the featured image, Doric columns have an undecorated square capital at their top.
I am sure you won’t get questions on ancient architectural styles in your GCSE Biology, but Doric (now DORIC) is perhaps a simpler way of remembering the key points to include in the experimental design questions in the exam. I have written about CORMS before and there is nothing new in this post, simply a new acronym.
D stands for Dependent Variable. This is what you will measure in your experiment. The mark is often for how you plan to measure the dependent variable, how frequently you will take measurements etc.
O stands for Organisms. What are the key variables relating to the organisms involved? If using a living organism in your experiment (other than humans) often this involves using organisms of the same species, the same age and sometimes the same mass. If you are using humans, you often need to standardise your groups for gender, health, age etc.
R stands for Repeats. If you do more than one replicate of each set of conditions, it allows you to see how reliable your method is and also allows an average result to be calculated. Think about how many repeats you think you would do: it depends on the experiment of course. In a laboratory experiment, three might be sensible, if you are growing seeds to investigate germination, you might grow 200 identical seeds in a tray…..
I stands for Independent Variable. This is the thing you are going to alter in the experiment. So how do you intend to alter it and over what range?
C stands for Control Variables: what are the variables that need keeping the same in every experiment in order to make the investigation a fair test? Think what other factors might affect the dependent variable other than the one you are investigating. And then think how you would keep them constant in an experiment. I would suggest you need to identify at least two or three of the most obvious control variables to ensure you get full marks.
Simple! DORIC is the new CORMS….
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!
