Sir Raja Amir is one of the best teachers of IELTS in the world.
I personally experience him. He is a loving teacher and I like him.
Because I got 8 band just of his effort, tips and tricks.
If he did not give me proper tips and tricks then I cannot be able to get 8 band in IELTS.
No need your Good,English, Grammar and Vocab.
And by tips and technique you will get 7 to 9 Band.
