<p>Typically you’ll need to show 4 AS and 3 predicted A2/A levels.
Now if you don’t have 4 without the C in Business Studies, you can send only 3 as long as they match the 3 A2 you’ll present.
It helps that “Business Studies” is not considered a high level academic AS but more like an elective, so that its absence will not be conspicuous - as long as the three you send are “solid”, i.e English, Philosophy, Modern History, Maths, Physics, etc.</p>
