What test should I take

I used to live in the US for 5-6 years and I had to finis highschool in 3 year (It's a 4 course), I had no knowledge of the lange so I had to start with ESL 1 until ESL 4, then after that I had to take English 9-12 which as many if not all of you know is the course that native speakers have to take in highschool, I also had to take my load of subjects necesary to graduate, I also took an advance pacement subject.

After highschool I had to go to a comunity college for two years without problems but I never took a certification exam nor got a BA while there, now I live in my home country (Mexico) and took a class to prepare me for the First exam but the profesor said that I didn't have to take the class to take the exam, they don't offer preparation for the CAE so I don't know how I will do, does anyone know which exam should I take if you were in my position?
