WJEC A-Level Biology Active Recall Guide
A question-and-answer revision guide for WJEC A-Level Biology, built to be worked in three passes rather than read.
- WJEC
- A-Level
- 36 topics
The 3-step active recall method
Re-reading notes is a futile process when your aim is to remember the information and successfully apply it in exam settings. Active recall is the method you use to ensure the information sticks for a long period of time. But even active recall can be futile unless you have a structured way of implementing it. This is where the 3-step active recall method comes in, a structured method that is signature to the Levo Learning guides.
-
Step 1
Answer up to 10 questions cold, closed book, even if you are unsure on the topic.
-
Step 2
Answer the same questions again, but open book. Write the correct answer down even if it seems pointless.
-
Step 3
Repeat as step 1 and answer the questions closed book again.
Worked across the WJEC A-Level Biology specification, one subtopic at a time.
The subject, and what is assessed
WJEC A-Level Biology is assessed by five units, two taken at AS and three at A2. The two AS units each last 1 hour 30 minutes and are worth 20% of the A-Level. A2 Unit 3 and A2 Unit 4 each last 2 hours and are worth 25%. A2 Unit 5 is a practical examination worth 10%. AS content remains examinable at A2, so first year material stays in use through the second year.
| Paper | Covers | Length | Weighting |
|---|---|---|---|
| AS Unit 1 | 1 hour 30 minutes | 20% | |
| AS Unit 2 | 1 hour 30 minutes | 20% | |
| A2 Unit 3 | 2 hours | 25% | |
| A2 Unit 4 | 2 hours | 25% | |
| A2 Unit 5 | Practical examination | 10% |
Memorisation, then application
Marks are given for applying content to the question that has been set, which cannot happen while the content is still being looked up. Step 1 shows what is actually held. Step 2 puts the correct wording in front of you while the gap is still fresh. Step 3 repeats the cold test, and the difference between the first and third attempt is the part that has moved.
Every question in the guide is paired with its answer in the same document, so step 2 is done from the guide itself rather than from a separate set of notes.

Sample questions
Taken from the WJEC A-Level Biology guide. Answer each one closed book first, then open the answer.
-
Chemical Elements Are Joined Together to Form Biological Compounds
What is the main biological role of the magnesium ion in plants?
Show the answer
Mg²⁺ is a constituent of the chlorophyll molecule, so it is essential for photosynthesis. -
Cell Structure and Organisation
What is the function of the mitochondrion?
Show the answer
It is the site of aerobic respiration, in which most of the cell's ATP is produced. -
Cell Membranes and Transport
Why is the membrane model described as fluid-mosaic?
Show the answer
It is fluid because the phospholipid molecules are free to move sideways within their layer, and it is a mosaic because the protein molecules are scattered irregularly through the bilayer like the tiles of a mosaic. -
Biological Reactions Are Regulated by Enzymes
What does it mean to say that an enzyme is a catalyst?
Show the answer
It speeds up a reaction but is unchanged at the end of it, so a single molecule can be used over and over again, and it does not alter the position of the equilibrium. -
Nucleic Acids and Their Functions
What type of reaction joins the three components of a nucleotide together?
Show the answer
A condensation reaction, which removes a molecule of water at each linkage. -
Genetic Information Is Copied and Passed on to Daughter Cells
Which stage of the cell cycle occupies most of the time, and why?
Show the answer
Interphase, because the cell must grow, make new organelles and proteins and copy all of its DNA before it can divide. -
All Organisms Are Related Through Their Evolutionary History
What is meant by a hierarchical classification?
Show the answer
Organisms are placed in a series of groups of increasing size, with each group contained entirely within the next larger one. -
Adaptations for Gas Exchange
What happens to the surface area to volume ratio of an organism as it becomes larger?
Show the answer
The ratio falls, because volume increases more rapidly than surface area.

Is the WJEC A-Level Biology guide a PDF?
Yes. It is a digital PDF sent to the email address on your order after purchase. Check the address is correct at checkout, and check junk or spam if it has not arrived.
Does the guide include the answers?
Yes. Every question has its answer in the same document, grouped by topic, so step 2 of the method is done from the guide.
