yes, it is useful. please use it and try to use proper grammar in your posts. it helps in improving your grammar. my grammar isn't rly that good and i refer to it once in a while.

believe me, it helps in your essays. people kept saying "write with powerful vocabulary". that isn't entirely true. even if your vocabulary is fabulous, having pathetic grammar spoils the whole essay. it's a chore to read and you'll definitely be marked down because of it.

read it now if you want an A.
