Hi and thanks for posting.
It sounds like you are fairly self-aware in terms of your strengths and weaknesses, and your assessment thus far sounds reasonable. It sounds like you've managed a lot at work from an early age and the more concrete achievements you have, examples of leadership, and examples of managing others if possible, the stronger your work experience sounds. Being a female, from North Africa, with such extensive international experiences, and the languages, plus solid work experience... schools will be interested in learning more about you. The GPA does sound like the greatest challenge. Taking courses this year is definitely recommended, as is using the optional essay space to share your story regarding undergrad. Yes no excuses, but it will help some if they like your profile otherwise. Within the top 15 in the US may still be feasible... especially outside the M7 or maybe top 10 or so, in my view. INSEAD and LBS will likely also appreciate your international perspective which is a key criteria they look for in applicants.
