Working in a busy service in my hospital, made attending IELTS preparation classes in my country difficult. I attended a few classes before doing the online course with Castel education for online classes. Castel Education sessions were more suitable to my working schedule. In addition, having private classes made me more comfortable with my teacher. Furthermore, my teacher was so helpful in correcting extra writing homework. It is a trustable online course and flexible for which I do recommend to any one.  All efforts to help me to get the IELTS  exam were really appreciated
