A good forward? (Is it possible?)

Little Zachary was doing very badly in math. His
parents had tried everything... Tutors, Mentors, flash
cards, Special learning centers. In short, everything They could think of to help his math.
Finally, in a last ditch effort, they took Zachary
down and enrolled him in the local Catholic school.
After the first day, little Zachary came home with a
very serious look on his face. He didn't even kiss
his mother Hello. Instead, he went straight to his
room and started studying. Books and papers were spread out
all over the room and little Zachary was hard at work.
His mother was amazed. She called him down to
dinner.
To her shock, the minute he was done, he marched back
to his room without a word, and in no time, he was
back hitting the books as h ard as before. This went
on for some time, day after day, while the mother
tried to understand what made all the difference.
Finally, little Zachary brought home his report card.
He quietly laid it on the table, went up to his room
and hit the books. With great trepidation, his Mom
looked at it and to her great surprise,
little Zachary got an "A" in math. She could no
longer hold her curiosity.
She went to his room and said, "Son, what was it? Was
it the nuns?"
Little Zachary looked at her and shook his head, no.
"Well, then," she replied, "Was it the books, the
discipline, the structure, the uniforms? WHAT WAS IT
ALREADY?"
Little Zachary looked at her and said, "Well, on the
first day of school when I saw that guy nailed to the
plus sign, I knew they weren't fooling around."
