I have done with my o levels with 5A* 2A and 1 B. Now I am starting my a levels. I am going to keep bio Chen physics and maths in a levels so I want to do it with good grades. I need guidance about as level that how the syllabus of these subjects is going to divide in as level and a levels. How many papers of these subjects I have to give in as level. I should I work hard?
