Grammar
1- Recite keywords or phrases. This can help you remember the structures easily. For example: “ever, never, yet and already for Present Perfect Tense”; “Have you done homework yet?”
2- Ask you friend to correct you. If you think you make mistakes when you write or speak, ask your friend, colleague or teacher to correct your mistakes.
3- Get accustomed to grammar terminology. When you study grammar, try to study grammar terminology such as adjectives, adverb, verb forms using books and materials.
4- Buy a grammar book as a reference. Analyze the book and check whether you understand the explanations or not before you buy it.
5- Recite the irregular verbs. Revise by leaving some time to recite.
6- Do not force yourself to speak and write correctly. To learn and understand the grammar rules are important but sometimes you have to feel free to express yourself. Making errors is a part of learning.
7- Always use the language. The best way to develop your grammar knowledge is to use it everywhere you can.
