How to remember English words with high efficiency

I do understand the problems you are facing. Because my native language was not an English. Once when i was in high school, i also have the same problems experiance, even kow i still havinp trouble writing the correct spelling. The method that i use was by grouping all the words, which have similar meanings into one group and the opposite words in other group. Then write 5 of them in big latters with the meaning and its opposite words. Then i put on my room wall or elsewhere, where i can see it more often. Once memorized, i replace with the following five words. That way, i more eazy and quick memorize those English words. That all my experiance during my times as student. Hope it help you.
