Especially in a G5 prestigious school like Oxford and Cambridge, grades are the entry threshold. After all, there are really many students who have won 3-4 A*. You can't receive an interview notice until your grades meet the standard. For ordinary schools, alevel scores and IELTS scores will basically determine whether you can enter the school.
Alevel's courses are mainly divided into:
1, core basic courses: mathematics, physics, chemistry, biology, geography, etc.
2. Extended courses of core courses: social biology, human biology, human physiology, etc.
3. Basic social science courses: history, philosophy, politics, economics, etc.
4. Applied science: computer, electronics, etc.
5. Art courses: music, art, etc.
6. Popularization of basic knowledge and skills: business studies, European studies, etc.
