Rate myself for a reference?

I asked one of my current professors to provide a reference for me on my application to the nursing program and she happily agreed. Today she sent me a form to fill out so she can be the best reference. This included a section where I have to rate the following:

On a scale of 1 to 5 (1=poor, 2=below average, 3=average, 4 =above average, and 5 =outstanding, NA=unable to evaluate) honestly rank yourself for each category:

NA 1 2 3 4 5 Intellectual Ability NA 1 2 3 4 5 Curiosity

NA 1 2 3 4 5 Lab Skills NA 1 2 3 4 5 Manual Dexterity

NA 1 2 3 4 5 Ability to work independently NA 1 2 3 4 5 Maturity

NA 1 2 3 4 5 Work in teams (Cooperation) NA 1 2 3 4 5 Knowledge of Microbiology

NA 1 2 3 4 5 Requires little supervision NA 1 2 3 4 5 Honesty

NA 1 2 3 4 5 Ethics NA 1 2 3 4 5 Ability to follow directions

NA 1 2 3 4 5 Ability to handle criticism NA 1 2 3 4 5 Neat personal appearance

NA 1 2 3 4 5 Written communication skills NA 1 2 3 4 5 Oral communication skills

NA 1 2 3 4 5 Ability to adapt to changing situations NA 1 2 3 4 5 Critical thinking skills

NA 1 2 3 4 5 Ability to make accurate judgments NA 1 2 3 4 5 Initiative

NA 1 2 3 4 5 Quality of work NA 1 2 3 4 5 Leadership

NA 1 2 3 4 5 Motivation NA 1 2 3 4 5 Sense of humor

NA 1 2 3 4 5 Emotional stability/Ability to work in stressful conditions

I feel a bit cautious doing this as I dont want to under or oversell myself. Any advice?

thanks!
