Hey
@saraeali,
It might be equal to a 36 IB however I am not completely sure. As an international applicant, to calculate your grades and their A-Level equivalent, what I used to do was going to a random UK university application information (let's say Oxford) for a specific course (maybe law) and you see the A-Level requirement and its equivalent based on the academic qualification you have and the country you have studied in. That was very useful in finding the equivalent to my Italian grades. I hope that helps!
Good luck!
I will caveat Axel's response here and say this is not always an ideal approach. I did this initially, but for whatever reason, most courses like Economics/Law at Russell Group uni's had relatively drastically higher requirements in my own country's A-level equivalents. For example, in England approx. 20% of A-level students in a given year will receive AAA or above grades in their A-levels. When I was looking at courses with AAB-esque requirements for UK applicants (so we are talking at least top 20% of test takers if 20% receive AAA) the equivalent grades you needed in my country would place you in the top 3% of results. I believe this is because they poorly interpreted the grade equivalents (e.g. comparing an A-level 'A' as like-for-like with another, when it is not the case).
What I would do instead is:
1. Explicitly state what percentile you came in nationally in your country's exams, if you can
2. Calculate your UCAS Tariff points - these can be a bit more accurate
3. Find the reverse - what are A-level entry requirements for universities in your own country? (This also helped me corroborate my claim, as my grades were rated as A*A*A* equivalent on webpages for UK applicants by universities in my country)
