This means that you will be require to pass at least 3 subjects at the GCE O (ordinary) levels standard, and at least 2 subjects at the GCE A (advanced) levels standard. Stating the fact that it has to be in 5 different subjects, that is to say that if you choose to count in English, Maths and Geography as the 3 subjects for O levels, then the 2 subjects counted in for A levels has to be different (that is, economics/science/literature et cetera, anything but maths or geography).

However, you did state in your question “or equivalent overseas qualifications.”. If you have not sat for the GCE O/A levels papers, you can try asking them if your current qualifications are eligible, as you didnt mention what kind of qualications do you current hold.

hope this helps.

In both cases “GCE” means “General Certfficate of Education”.

I suspect that you will probably fulfill the requirements providing you have graduated high school and studied a variety of subjects. I would suggest that you contact them and ask what they consider to be the equvilent Indian qualifications – most educational establishments have a list of these which they work to. Good luck with your application!
