well i dont think that old 42 y/o have exam
He is a tutor and he is busy teaching students with no respect like you.
He is a MATH AND PHYSICS teacher NOT biology.
He is the owner of this place and another 6-5 websites FULL of resources and he is working on all of them to make them avaliable for students.
If this is how we get treated from a member like you, THEN YOU ARE NOT NEEDED in this place. You could've at least thanked me for looking for u in google but all what you did was post a rude comment.
If you search this forum you will find what you want was posted already butt you want us to get you everything for you as if we are sitting and doing nothing. As if we don't have exams.
