IGCSE vs GCSE

Are they equivalent?
I am an international student applying to law this year, and I have taken 5 IGCSEs.
Would I be disadvantaged given most UK applicants have taken more GCSEs or it wouldn't matter because predicted grades are more important?

Take a look a the universities you are interested in and see what their GCSE entrance requirements are. Really its only medicine, dentistry and vet science where they state a minimum of 6/7 GCSEs, for most other courses they require maths and English push a range of other GCSEs so your 5 IGCSEs would suffice. In actual fact, the ICSE exams are easier to pass than the GCSE exams and unis should really seek higher grades for IGCSE applicants but most don't bother. Some of the private schools in the UK get their students to take the IGCSE syllabus since they know more of their students will get higher grades and the unis won't be bothered. It's a bit of a loophole which unis need to address.

Saw some older threads about IGCSEs and GCSEs- there were in fact mixed reactions on whether IGCSEs were easier or not.
Anyways, I researched that most of my applied uni courses are (luckily) more flexible on the weighting of GCSEs for int students. In my location I’m doing 7 A-level equivalent subjects, so I hope they are more lenient on IGCSEs/GCSEs.
