Hello,

There are some ways in which your english can be improved for competitive exam point of view. You can buy 'Plinth to paramount' by Neetu singh which covers grammar topics and the book is quite good. You can buy 'word power made easy' book which will help you develop your vocabulary and this book is really good and will definitely help you. You can watch some you tube videos for some topics in which you have doubt. There are many apps available in playstore for grammar and spoken english you can check those. And you can also download free pdfs of the books I have mentioned above as they are available on many sites for free. Improving english is not difficult now a days. Do not worry about english. And have confidence and faith. Thank you and all the best
