FAQs

Read some of our most frequently asked questions and answers

How can I effectively revise complex biological processes, like photosynthesis and respiration, for the IGCSE Biology exam?

To memorise these processes, create detailed flowcharts or diagrams. Write key steps and chemical equations. Additionally, use acronyms or mnemonic devices. For example, "Piglet Ran Cautiously" can help remember the reactants in photosynthesis (Piglet for Pigments, Ran for Water, Cautiously for Carbon dioxide).

What's the best approach for memorising the names and functions of different cell organelles?

Visual aids like flashcards with images and brief descriptions are helpful. For instance, you can associate the mitochondria with "powerhouses" and draw a small generator next to them on your flashcards.

How can I remember the classification of living organisms, such as the five kingdoms of life?

Mnemonics like "Dear King Philip, Come Over For Good Soup" can help remember the order of the five kingdoms (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species).

What techniques can I use to remember the stages of the cell cycle (Interphase, Prophase, Metaphase, Anaphase, Telophase)?

Create an acronym like "I Prefer My Aunt's Tea" or create a catchy phrase for each stage, such as "In Paris, My Aunt Tans."

How can I efficiently revise and memorise key biological definitions and terminology?

Make flashcards with the term on one side and the definition on the other. Quiz yourself and review regularly. Try grouping related terms, creating a word map, or using the method of loci, associating terms with specific places or objects in your environment. You can do this by using sticky notes and creating an association with where your notes are in relation to certain parts of the room. This may help you visualise your notes in the exam.
