What is WJEC AS Level Chemistry?
WJEC (Welsh Joint Education Committee) AS Level Chemistry is an advanced subsidiary qualification typically studied during the first year of post-16 education in Wales, England, and other regions where the WJEC syllabus is recognized. It serves as a stepping stone toward full A Level Chemistry and can also function as a standalone qualification for students seeking to develop their scientific literacy.
The course emphasizes understanding core chemical principles, applying scientific reasoning, and developing practical skills through laboratory experiments. It prepares students for further studies in chemistry or related disciplines and enhances critical thinking, problem-solving, and analytical skills.
Structure of the WJEC AS Level Chemistry Course
Syllabus Content Overview
The WJEC AS Level Chemistry syllabus is divided into several key modules, each focusing on different aspects of chemistry. The main areas include:
- Atomic Structure and the Periodic Table
- Bonding and Structure
- Energetics
- Kinetics
- Chemical Equilibria and Le Châtelier’s Principle
- Inorganic Chemistry
- Organic Chemistry
Practical Skills Component
Practical skills are an integral part of the WJEC AS Level Chemistry course. Students are expected to develop competencies in:
- Planning and conducting experiments
- Recording and analyzing data
- Drawing conclusions
- Evaluating experimental procedures
Practical assessments often include a series of core experiments that are assessed internally, contributing to the overall qualification.
Assessment Methods
Written Exams
The assessment for WJEC AS Level Chemistry primarily consists of two written examinations:
1. Paper 1 – Multiple Choice and Short Answer Questions
- Focuses on fundamental concepts and calculations
- Typically lasts 1 hour and 15 minutes
2. Paper 2 – Structured Questions
- Covers broader topics, including practical data analysis
- Usually lasts 1 hour and 30 minutes
Practical Endorsement
While the practical skills are assessed internally by teachers, students also receive a practical endorsement as part of the qualification, which is recorded on their certificates. This endorsement confirms competence in practical techniques and data handling.
Key Topics Covered in WJEC AS Level Chemistry
Atomic Structure and the Periodic Table
