Efficiency

Functions are fully utilized to reduce the amount of repeated code. Very efficient code.

Some functions to reduce the repeated code. Fairly efficient code.

Few to no functions. Code is inefficient in places.

No functions. A lot of repetition and inefficiency.

Comments

Comments are elegantly written. Pre and post conditions are well handled.

Comments explain program sufficiently. Pre and Post conditions attempted.

Comments are present before majors ifs and loops.

Too few comments. Pre and post conditions needed.

Code Structure

White space and tabbing is used expertly to format code.

White space and tabbing is used in the code.

Code is hard to read in sections because of missing white space or tabbing.

Code appears messy. It is very hard to read.
