Whenever I got my answer sure I have to accept it is the best token of appreciation, also my problem is English is my second language and I have been learning it during this 4 years in the U.S. I entered here when some of you guys or anyone use irony or like that to be honest hard to understand may some of question like this PTE is because of this problem, sorry about that. But if your reply will be since English is not my native language and I have to leave this community I can get out no worries.
