What's the point of getting an A?

It could be a purpose but why would it be a purpose?

Purpose formula is something like this

A am [... ] so I can [goal / desired outcome] = purpose

A purpose explains what you are doing so you
can reach a goal. It's one of the many things you do towards the finished product.

Like baking a Fruit cake.

I am turning on the oven so I can have fruit cake. = purpose

I am adding the flour and fruit so I can have fruit cake = purpose

I am mixing the batter so I can have fruit cake.

Or someone else might say, I am 'taking my car keys', 'driving to the shops', 'searching the isle', 'buying the fruit cake', so I can have fruit cake.

(As they say there is more than one way...)
