example example example... give specific example to support your reasons. I already talked about this on your previous essay. Therefore, i am not going to bore you by saying the same thing here.
another problem with your essay is, your word count is low. Moreover, your body para is too brief. Make those elaborate. The easiest way to make a good size body para is writing specific example.
Don't introduce new idea/reason in your conclusion. This will hurt your score.
It is cost effective and there is a pool of opportunities available now to accomplish the same.
you have not mentioned anything that supports learning new language in one's homeland will be cost effective. however, you wrote learning new language from a foreign country requires more money; we can infer the cost effectiveness from this. but, don't do that. Try to write as clearly as possible. Always remember, as much work load as you put on your reader/grader, that much chance of losing score you have increased. So write clearly and perfectly.
wish you all the best :)
