Likelihood of a Tiffin Boys offer with these GCSE results

[RoseTulips2023]

My son has just had his GCSE results - 7 9s and 4 8s. The 9s included Maths, Further Maths, Physics, Biology and Chemistry. He wants to do Maths, Further Maths, Physics and Psychology A level. He has submitted his grades to Tiffin Boys. Just wondered what the likelihood of getting an offer was? Thanks.

The grades are fine but for maths and physics there are usually very few external places for boys- so no guarantee.If he were applying for languages & humanities then he would have a much higher chance.

Thanks very much.
