Well... if you are using non-english words like "dis", "cuz" and "plzzzz" I'm not surprised.
Your education is what you make of it... if your grades need to be higher.. you need to spend more time studying and less time fooling around. And just doing what your teacher assigns might not be enough... you can do more.

That type of "go over and beyond" attitude sometimes makes the difference between being a great success and just getting by in life.

Smoothly is correct--proper spelling should be used at all times. Your grades are going down, which means you need to study more. School is supposed to be more difficult each year, or you wouldn't advance in knowledge. Study for tests earlier, speak to your teachers about your declining grades. We are there to help you!
