Students also need to know how many papers they must answer in the examination and the nature of these papers. Candidates who have studied the Core syllabus, or are expected to achieve grade D will sit for the following papers. Students who have studied the Extended syllabus Core and Supplementand who are. Candidates are required to demonstrate a sound knowledge and understanding of the following aspects:.

Moreover, they will also be asked questions that require them to apply this material to unfamiliar contexts and to apply knowledge from one area of the syllabus to another. Students are required to read, organize, calculate, report, present, analyze and relate scientific data.

They may do this in words or in the formal of graphical interpretations, tables, calculations, patterns, and other relationships.

Predicting hypotheses and solving problems including scientific relationships is also a vital factor. Questions based on this objective may be from subject content familiar or unfamiliar to the student. Students must make sure they manage time well and allocate time to answer easy and difficult questions together. If for example, the difficult questions require more time, then candidates must focus on the easy.

Paper 3 and 4 require students to answer short questions that need short answers, calculations or diagrams. Paper 5 and 6 are practical papers that consist of a variety of questions with a varied number of marks.

Take a look at our top tips on how to best study for IGCSE exams to sort out all your revision worries. Students will score the marks they need when they use the main keywords and terms that have marks allocated to them. Students must use a variety of tools like highlighting and underlining that can help them memorize such keywords.

In addition to that making, short notes will help store all the keywords in the long term memory. Finding the right textbooks that can help you study can be tricky, use this guide to find out what textbooks you need for IGCSE Biology:. Understanding question words is a critical part of answering exam questions and scoring good grades. Questions testing objectives of understanding and knowledge will have question words like; define the state, describe and explain.

Other questions testing for evaluation and problem solving or experiments will have question words suggest, predict, calculate or determine.

Long essay questions on comparison and analysis questions will begin with; analyze, evaluate and assess.

Each word has a purpose, answering questions based on what the question word is asking is key to scoring better. Examples, calculations, diagrams and equations are all part of the understanding and knowledge objective.

The examiner should be able to see that the student is confident in applying the knowledge learnt to different concepts. Put an X on Fig. A …………………………………………………………………………………………………………………………….

D ……………………………………………………………………………………………………………………………. They are fed on high protein food made from animals. When eating this food, the fish are feeding as secondary consumers.Biology is a very content-heavy science, but the IGCSE examiners tend to be quite lenient- the mark schemes provide about 10 points to cover a four mark answer!

To score in biology, all it takes is a bit of hard work and memorization. The best way to study for this is to find a nice, quiet place free of distractions- and to make your studying interesting and memorable. I take notes on biology and write down precisely what we need to know according to the syllabus, nothing more and nothing less.

Of course, it gets extremely monotonous. I have a strong interest in neuroscience, so I do more research into that just as a pet project. There are a lot more chapters to biology I broke them down into sections that may not correspond exactly to the syllabusbut I assure you they are complete:.

Day after tomorrow i have my biology paper Please reply fast I am very worried about my last exam. Sanjeev I hope you finished your March igcse papers so can you tell me how is the new syllabus pattern and some hard questions or any rare questions you have noticed.

Plz email me aeshajassim27 gmail. Please can you send me a copy of your notes? Please I really really need them fo Tuesday. Your notes are excellent! All I can say, is well done! I wish you all the best at university and feel sure that you will do well whatever your career choice.

Oh my god. Your notes are amazing. Got 2 bio tests tomorrow.

Please email me at matrix standrews. Hi, I really like your notes on classification and how much effort you put into them.Starting from onward, there are some major changes to the syllabus and additional of several new topics.

By exposing students to interesting biology concepts with practical demonstration, it will ease the understanding. With a strong focus on fundamental knowledge development as well as thinking out of the box, we prepare our students for biology subject at secondary levels and beyond by providing advanced materials. Our goal is to establish a firm foundation on each topic in biology, stretch students further and stimulate their interest in the subject by injecting real world application of biology.

Most organisms are able to move their whole body even plants can shift their stem towards the sunlight and their roots move towards healthy soil. Anaerobic Respiration which is the incomplete breakdown of food. Happens when there is not enough oxygen.

It is the permanent increase in size and quantity of cells using materials absorbed from the environment. It is removal of harmful products of metabolism. Unit 2 : Classification Classification is sorting organisms into smaller groups based on their similarities which then allows us to make comparison between them. A specie is a group of organisms that share the many similar appearances and can bread with each other.

Species are scientifically named by two names in Latin to avoid differences in languages. The first name is the name of the genus while the second name is the species name e.

The main groups of living are the 5 kingdoms. Virus The size of a virus about nm and its only visible with an electron microscope. It has no cell structures. Bactria The size of bacteria is about 0. It is only seen under high powered microscopes. Structure: No Nucleus. Yeast budding. Single fungi cell Structure of a mould fungus. Budding is when a yeast cell splits into two cells and it keeps happening over and over again numbers can get up to millions in just a day. The plant kingdom is divided into algae, ferns, mosses, and seed plants.

Seed plants are divided into conifers and angiosperms. Angiosperms are devided into two groups Monocotyledons and Dicotyledons. Feature Monocotyledons Dicotyledons Seed Seed containing one Seed containing two cotyledon cotyledons Leaves Leaves containing parallel Leaves containing branched veins veins Root Fibrous root system Tap root system with lateral adventitious roots. The chordates and the invertebrates. The invertebrates consist of Nematodes, Annelids, Molluscs and Arthropods.

Arthropods are divided into insects, crustacians and arachnids. Adaptation to insects on life on lands. Chordates or Vertebrates Chordates are vertebrates which are animals with back bones they consist of: Fish, Amphibians, Reptiles, Birds, and Mammals.A specie is a group of organisms that share the many similar appearances and can bread with each other.

Species are scientifically named by two names in Latin to avoid differences in languages. The first name is the name of the genus while the second name is the species name e. The main groups of living are the 5 kingdoms. How a virus multiplies 1. The genetic material multiplies 3. New viruses are formed inside the cell and then burst out of the cell. Comparison between Annelids, Nematodes and Molluscs.

Arthropods are divided into insectscrustacians and arachnids. Differences between plant and animal cells:. There are factors that affect photosynthesis changing these factors are: Temperature, Light intensity, and concentration of carbon dioxide. Factors affecting rate of transpiration. Blood travels via arteries until it reaches smaller vessels called capillaries. It is here that materials are exchanged between blood and the tissue cells. Smoking causes a number of diseases, some of them are life-threatening.

It means the ability of the lens to detect far and near objects by changing its thickness to be able to see far and near. Search this site. I hope that you find this website useful!
