International foundation year

i’m applying for a foundation year at king’s because my a-levels are a mess, but i’m feeling apprehensive about whether they’ll require additional grades for me to get accepted. if they do give me an offer, would they need me to submit my summer exam results, or would i just need to provide my IELTS score? i’ve already sent them my high school transcripts from the past three years, along with my IGCSE results, but i’m worried that the offer might be conditional and require more qualifications than i currently have.
