The GCE A-Levels qualification places emphasis on in-depth knowledge, deep understanding, strong reasoning abilities and critical thinking. It is arguably the most widely recognised pre-university qualification in the world, readily accepted as proof of superior academic ability for entry into world-class universities around the world. The Cambridge A-Level curriculum provides a firm bedrock of fundamental knowledge by guaranteeing comprehensive coverage in the breadth and depth of each subject offered. Students are assessed for their mastery of subject matter, their application of knowledge and understanding to everyday scenarios and their ability to think critically in unfamiliar situations. In the Sciences, a fair part of the assessment involves the demonstration of laborator-based skills.
