Figuring out what the assessment objectives require in the IGCSE Biology examinations will help students answer the exams better resulting in the receiving the highest grade. Basically, assessment objectives show students what is required of them in the examinations. Once students master that, examiners will know that students have learnt what they were supposed to. Students also need to know how many papers they must answer in the examination and the nature of these papers. Number and Nature: Core and Extended All candidates take THREE papers as mentioned in the Cambridge Examinations Website  Candidates who have studied the Core syllabus, or are expected to achieve grade D will sit for the following papers Paper 1, Paper 3 and EITHER Paper 5 or Paper 6 These candidates will be eligible for grades C to G Students who have studied the Extended syllabus (Core and Supplement), and who are expected to achieve a grade C or above will sit for the following papers Paper 2, Paper 4 and EITHER Paper 5 or Paper 6 They will be eligible for grades A* to G. Assessment Objectives for IGCSE Biology 2022 Knowledge and Understanding 50% Candidates are required to demonstrate a sound knowledge and understanding of the following aspects: Scientific phenomena, facts, laws, definitions, concepts and theories Biological and scientific vocabulary, terminology and conventions Instruments and apparatus, including techniques of operation and aspects of safety Technological and Scientific applications with their social, economic and environmental implications. Students are asked to recall and explain these important aspects throughout their assessments. 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. 2. Handling information with Problem Solving 30% This objective deals with analysis and manipulation of scientific data. 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. 3. Experimental Skills and Investigations 20%  Experimental and Investigative skills are given importance in this objective. In addition, Examiners look for the skills listed below to reward points. Dealing safely with scientific instruments and apparatuses of measurement or experimentation. Planning scientific experiments Understanding the wisdom behind the scientific method Reporting and presenting data or results collected from the procedure. Interpreting and evaluating the results Analysis and suggestions based on the results and the procedure   General Tips For Students for IGCSE Biology 2022 Time Management Time Management is a key factor in all IGCSE Biology papers. More importantly, for Paper 1 and 2, which are multiple-choice questions. Furthermore, multiple-choice questions require students to be quick and steady. 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 ones first and after that, go back to the tough ones. Paper 3 and 4 require students to answer short questions that need short answers, calculations or diagrams. It’s important to note the number of marks allocated for each question. Usually, 1 or 2 mark questions are quick and easy. 2 or more mark questions require more timing and description. Paper 5 and 6 are practical papers that consist of a variety of questions with a varied number of marks. Students must be prepared for different questions and most importantly, manage time efficiently. Try Tutopiya’s printable study and revision planners to help you plan your revision schedules. Take a look at our top tips on how to best study for IGCSE exams to sort out all your revision worries.   Keywords and Key terms in Answers IGCSE Biology is an examination that wants students to use the correct keywords, concepts and terms. Students will score the marks they need when they use the main keywords and terms that have marks allocated to them. It’s important to memorize and understand the key terms and definitions for each chapter of theory. Above all, theoretical concepts and terms must be used when answering questions. 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.

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. Importance of Diagrams, Equations, Calculations and Charts Essay Questions According to the requirement of the question, providing the right example is important. Examples, calculations, diagrams and equations are all part of the understanding and knowledge objective. These tiny details will only propel the student forward. The examiner should be able to see that the student is confident in applying the knowledge learnt to different concepts.   Why Practice is Important Ever heard of the phrase practice makes perfect? Practice helps students to face the papers in the examination confidently. Every student is different and approaches the papers in different ways. Above all, this process helps students familiarize themselves with the answering process. In other words, practising past papers is a vital part if revision. Students can benefit in several ways from practising past papers as follows: Learning to manage time Noticing a pattern in the questions Mark allocation How to approach questions Allocating time for past paper practice in your study plan and schedule is a very vital step. No revision session is complete without a past paper practice session.
