To excel in English grammar, it's essential to practice regularly and understand the rules. Start by learning the basic concepts such as nouns, verbs, adjectives, and prepositions. Practice identifying these parts of speech in sentences.

Next, focus on sentence structure. Learn about simple, compound, complex, and compound-complex sentences. Practice constructing sentences using various structures to improve your writing skills.

Use resources like grammar books, online tutorials, and apps to supplement your learning. Keep a notebook to jot down new rules and examples you encounter.

Lastly, reading and writing in English will help you internalize the rules. Immerse yourself in English literature, articles, and even social media to improve your understanding and application of grammar.
