English Grammar Academy is a free iPhone application developed by Parth Dabhi. Designed for learners at all levels - beginner, intermediate, and advanced - this app offers over 3200 grammar exercises divided into various subjects of life. With a fun and interactive approach, users can learn and practice English grammar effectively.

The app provides a comprehensive range of questions in three levels, allowing users to progress at their own pace. Each level is further divided into detailed subject-wise exercises, ensuring a thorough understanding of grammar concepts.

One of the standout features of English Grammar Academy is its immediate feedback system. When a user makes a mistake, the app highlights the incorrect answer in red and displays the correct answer in green, enabling users to learn from their mistakes.

Upon completing an English test, users can view their performance and identify areas where they excel and areas that require more practice. The app uses a three-scale rating system, indicating the user's percentage score and color-coding it from bad to perfect. If a user's total score is colored green, they are ready to move on to the next level.

English Grammar Academy caters to learners of all levels - from beginners to upper-intermediate - making it an excellent resource for anyone looking to improve their grammar skills. By participating in exercises at least twice a week, users can enhance their English grammar proficiency in a fun and engaging way.
