Pls answer me asp.
Have a look at this website: http://www.thefreedictionary.com/ Your text is full of bizarre misspellings. At least check the meanings of "guy" and "gay".
There is a big difference between "true" (exists in reality) and "correct" (without errors). Your question should be, "Is this correct?"
Your message is understandable, but certainly not correct. I guess you are sending a message to your teacher, so greetings like "hi" or "hey" are not appropriate. Neither are exclamation marks (!). Here's a corrected version.
"Hello, do we have an exam today? If so, could we change it to another day?"
I wonder why you want to avoid an exam.
