Result:

I started my schooling as the majority did in my area, at the local
[-primarry-] {+primary+} school. I then went to the local [-secondarry-] {+secondary+} school and
[-recieved-] {+received+} grades in English, Maths, [-Phisics,-] {+Physics,+} Biology, Geography,
Art, Graphical Comunication and Philosophy of [-Religeon.-] {+Religion.+} I'll not
bore you with the 'A' levels and above.

Notice the [-ambigous-] {+ambiguous+} English qualification above. It was, in truth,
a [-cource-] {+course+} dedicated to reading "Lord of the flies" and other gems,
and a weak [-atempt-] {+attempt+} at getting us to [-commprehend-] {+comprehend+} them. [-Luckilly-] {+Luckily+} my
middle-class upbringing gave me a head start as I was [-was-] already
[-aquainted-] {+acquainted+} with that sort of [-langauge-] {+language+} these books used (and not just
the Peter and Jane books) and had read [-simillar-] {+similar+} books before. I will
never be able to put that [-paticular-] {+particular+} course down as much as I desire
to because, for all its faults, it introduced me to Steinbeck,
Malkovich and the wonders of Lenny, mice and pockets.

My education never included one iota of grammar. Lynn Truss points
out in "Eats, shoots and leaves" that many people were excused from
the rigours of learning English grammar during their schooling over
the last 30 or so years because the majority or decision-makers
decided one day that it might hinder imagination and [-expresion-] {+expression+} (so
what, I ask, happened to all those [-expresive-] {+expressive+} and imaginative people
before the ruling?).
