A Level Biology WJEC Unit 1&2 (AS)

About Course

This A Level Biology revision course is carefully structured to support exam success, with one sub-unit covered in depth each week. The course begins by revisiting Unit 1 topics studied last term before progressing through Unit 2 content. All required material for both units will be covered ahead of the exams, with the final weeks focused on full past paper practice and exam technique to ensure students are confident, knowledgeable and well prepared. Each lesson and unit can be revisited an unlimited number of times, giving you complete flexibility in your revision.

Covering the entire Unit 1 and 2 specifications, the course combines high-quality teaching with a wide range of engaging resources, including:

Several weekly interactive lessons
Comprehensive video explanation of the topic
Extensive quizzes, with questions covering all points of the specification
Past paper questions broken down into sub topics, coupled with model answers for self assessment- so you don’t have to try and figure out complicated WJEC mark schemes!
Flashcards
Revision sheets
PDF summary of each sub topic
WJEC Knowledge Organiser
Full past paper walkthroughs
Our Q&A feature provides direct access to expert tutors, allowing you to ask questions and receive clear, personalised support
More activities to follow.

Whether you’re a Year 12 student starting your A Levels or a Year 13 student preparing for a resit, this course provides everything you need for success in Unit 1&2.

Course Content

Unit 1.1 Biological Compounds
All organisms are composed of biological molecules. These are fundamental to the functioning of living organisms. It is essential to understand how the structure of these molecules is related to their function.

Lesson 1 – The Importance of Water and other elements
Water and Elements
Lesson 2 – Carbohydrates

Carbohydrates

Unit 1.2 Cell Structure and Organisation
All organisms are composed of cells. The cell theory is a unifying concept in biology. The theory states that new cells are formed from other existing cells, and that the cell is a fundamental unit of structure, function and organisation in all living organisms. The understanding of the ultrastructure of cells has been developed through advances in microscopy.

Unit 1.3 Cell Membranes and Transport
Cell membranes are essential in the control of the movement of substances into and out of the cell. They also play a vital role in cell recognition.

Unit 1.4 Enzymes
Enzymes are vital in controlling metabolism in organisms. Scientists’ knowledge of their structure and function has enabled enzymes to be used extensively in industry.

Unit 1.5 Nucleic Acids
Nucleic acids are common to all living organisms and are essential for many functions including inheritance and metabolism.

Unit 1.6 Cell Division
This topic covers cell division. During the cell cycle, genetic information is copied and passed on to daughter cells.
