Of the colleges you apply to, each has a reader who specialized in a certain region. All of the applicants from a certain region are read by the same reader. Since you are living in Dubai, your reader may only be familiar with the local Dubai educational system and may not understand the Indian CBSE system. I thought that you were studying under the British style education (A levels, GCSE, etc).
Even so the AP scores are self-reported. Because of this they are given less weight than if you were to take an SAT II subject test instead. For these reasons, I would focus on taking the relevant SAT II test for the core subjects (Math, language, science) instead of AP exams, as these will be more recognizable.
