What are they? 

A Levels are considered the traditional academic route after Year 11, and students usually pick a combination of three. A Levels are designed to demonstrate to universities and employers that you have a range of relevant skills. A Levels typically take two years. You are graded A*-F. 

Why? A Levels are considered a very competitive qualification for getting into university, and the most competitive university courses may only accept A Level qualifications because of their academic focus. A Levels also give you the chance to study a wide range of subjects, meaning you can keep doors open if you are not certain about what you want to do in the future.
