How to study/review english grammar effectively?
Though it is an extremely long and tedious process learning English grammar, esp the parts of speech, it would be practical to start with nouns, pronouns, verbs, tenses and adjectives. Once you can construct simple sentences, then you may go on to more complex ones using conjunctions, adverbs, etc. Do lots of slow reading everyday and identify the various parts of speech. Get someone to guide you along so you may progress 3 times faster. At the same time, do not neglect your spelling of words and also building up your vocabulary at intermediate, then advanced level. Good luck on your journey!
