How can I improve my arabic

Hello,

i would like toimprove my arabic skills in reading and writing with applications of the grammar rules. I can speak arabic dialect and in most times i have no problems to understand a conversation. But if it comes to arabic Fus `ha then there my weak points are lying. It is difficult for me to understand that words in dialect are not the same as in written. yet i have not tried out to read sth. Most of the text as newspapers or stories are written without the vocalisation (harakat) of the spelled word while i actually need the written words with the  Kusur, fatha etc. to improve my reading and by then getting used how i use those signs on the word beginning and end.

I m learning to get used now to writing with the Rosetta stone and it is in some way helping but only for one word at a time. I m living at the moment in an arabic country where i study, too. so it is recommended for me that i take the arabic course,that is what i know up to date and because i  dont want to fail this course i am asking YOU to help me out. The course will be due in 2 years, so i have still time, better to be prepared than to be late.
