Latymer Upper School Sixth Form - GCSE predicted grades

Hi, I'm going into Year 11 this year I'm going to apply to The Latymer School Sixth Form for 2017 entry and I want to know if these GCSE predicted grades are good enough for consideration of an entry.

My predicted grades:

English Lit: 7
English Lang: 7
Maths: 7
Business: A*
Computing: A
History: A*
Biology: A
Chemistry: A
Physics: A
Spanish: A

In general, I feel that I am a high ability student capable of getting A* in all my subjects.

I know that I will have to take a test but are my predicted grades good enough?

Also, just wanted to include that I want to do Maths, Economics, Biology and Chemistry for my A levels.

Would gladly appreciate your thoughts about my predicted grades and if they would be good enough for consideration at Latymer Sixth Form
