1.   Hoping will not help in your English proficiency.  Hard work will.  So I feel this sentence is useless.  Your essay is strong and well structured enough to end without any extra sentences.  If you really must write something, write something like, "I need to double my effort in mastering this important language."  In my opinion this extra sentence is like 劃蛇添足.
