Hello Gissem, and welcome to the forum.
Note that while "Hey" may be okay among friends or people on familiar terms, it is not suitable here. Use "hello" if necessary, or even better, just ask your question without any introduction.
See above. Consider also specifying your degree. For example, "I recently graduated with a Bachelor of Arts from the Department of History at Oldham University".
Let us know if you need further help with your statement of purpose.
