is my English correct?

The Lord is my teacher,
He makes me stay awake in my studies all night;
He leads me from page to page.
He restores my sanity;
He guides me in the path of conciousness,
for my GRADES sake...
even though I grow weary in the shadow of books,projects,assignments, activities,etc.
I fear no deadline for submission/ test.
for Thou art with me.
Thy rod and Thy staff they keep jabbing me....
Thou wilt prepare a test for me in
the presence of my classmates...
THou hast crammed my mind with so much knowledge;
my eyelids droop.
Surely a good grade and a kind teacher
will follow me after the test,
or I will dwell in the class forever!
