Chalk up is an idiom which means to give credit to something or to attain something. It comes from the literal act in the 16th century of writing a debt that was owed to a store in chalk. Usually it is found in the phrase chalk it up to.

A chock is a wooden block used beneath wheels to prevent movement.

Chock-full means completely full. It is hyphenated as one word. Common misspellings are chockfull and chock full.

And chock-a-block is an informal word meaning crammed to capacity. Used mainly outside the US. Though there is an Americanized spelling, chockablock, listed in the dictionary.
