SEO Strategy: One Page vs. Country-Specific for GCC IELTS Keywords?

We will run an IELTS practice platform that helps users improve their English skills to achieve a good IELTS score. Our current focus is on GCC countries (Saudi Arabia, UAE, Kuwait, Qatar, Bahrain, and Oman).

We are optimizing our content around “IELTS reading practice” and similar keywords, which have the same user intent across all GCC countries.

The question is: What’s the best SEO approach?
1️⃣ Use one page targeting all GCC countries with a general structure:
mywebsite.com/en/ (English)
mywebsite.com/ar/ (Arabic)

2️⃣ Create separate country-specific pages for the same keyword, with a structure like:
mywebsite.com/sa-en/ (Saudi Arabia – English)
mywebsite.com/sa-ar/ (Saudi Arabia – Arabic)
mywebsite.com/uae-en/ (UAE – English)
mywebsite.com/uae-ar/ (UAE – Arabic)
(And so on for the remaining GCC countries)

Which approach would be more effective for SEO, ranking, and user experience?
