I prepared for IELTS with JAK Global Education and was generally benefitted by the learning experience. The teachers told me the structure of the exam well, and they provided me with useful comments on the ways in which I practice my speaking and writing skills.
I particularly enjoyed the practice sessions, as I learned the areas I needed to focus on and developed my skills in them beforehand. The teachers were also available when I had questions.
If you are interested in IELTS exam preparation in uae, I would recommend looking at the course information and discussing it with the institute before deciding.
