How to improve English writing
1- Revisit English grammar. Tenses, punctuations, parts of speech stuff. It is vital that the basics be strong, only then you can build up on it. 2- Start reading some quality English daily. By reading it you will be unconsciously assimilating rich vocabulary, various sentence structures and expressions etc. 3- Start with writing one page articles and get them checked by a competent English teacher. There are no short cuts to becoming an articulate writer. There’s only one rule: write, write and write more. The more you write, the more mistakes you will make while playing with different words, expressions and sentence structures. 4- When your teacher gives you a go ahead that your articles are error-free, you can move on to writing expansions of about 250-300 words. Plus you can start practising other items like comprehension, précis, direct indirect etc.
