Even though this is not the final place you want to sent this to, it is still helpful if you can capitalise words. If not, teachers may assume you don't know this at all and teach the basics.
1. All place names, eg Riyadh, Saudia Arabia and organisations, abbreviated names and their initials (SA, HIJRL,) are capitalised in English. Headings require capitals eg Personal exhibitions.
2. I also suggest a few more separate headings for different sections. It's not too easy to follow the information eg. 'Education', 'Employment history' etc.
3. The order of employment can be in chronological or most recent first.
4. Since you include both dating systems I think it's a good idea to indicate Gregorian calendar, not just Gregorian, and indicate what 'hijri' means at the beginning of the curriculum vitae CV(?)
I hope this is helpful.
