I took IELTS on 5 April and I've just recieved my grades. I've got a 7.5!!! The book called "IELTS Target band 7 by Simone Braverman" was a great help, I really recommend you to read it, because it will teach you how to approach the exam. Good Luck!

Always start with their topic blueprints. Make sure you understand each section and what that exam is trying to test. Understanding the format of an exam helps you improve your score by 30%.

For TOEFL, I urge you to find some book approved by Educational Testing Service (ETS) It would be a great help for you. Moreover, you must read different topics like, history, literature, arts, science and so on. Of course, with speaking to native speakers it would be easier for you
