Person after clearing IELTS gives tuition for English vocabulary words and grammar.

Navneet was my classmate in school and since those days he was like THE Scholar of English literature. He used to teach us in groups and was the main reason behind our great grades. His methods are good, storytelling method which he applies to make you understand the topic is a tremendous success and his knowledge of grammar and his methods of teaching to make his students learn grammar is great!
His vocab is great and particularly vast!
I would recommend that you take atleast one of his classes to experience his odd but effective methods to learn english.

Navneet has a skill of explaining everything in the utmost simple and student friendly way.
