When learning English, I find grammar the most challenging and I have done several things to improve it. Firstly, I have a good grammar book. I do the exercises in the book, and whenever I have a grammatical question, I quickly refer to it. The book makes me more confident in writing and speaking. Secondly, I read English books. When I read, I come across different grammar rules. This helps me learn and remember grammar naturally. Last but not least, I learn grammar from teachers and friends.
