Final answer:
A greater sense of accomplishment represents a subjective measurement of progress towards an academic goal.
Explanation:
Subjective measurement of progress towards an academic goal refers to personal feelings and perceptions rather than tangible outcomes. In this case, a greater sense of accomplishment would represent a subjective measurement as it reflects an individual's personal satisfaction and fulfillment with their progress.
On the other hand, improved grades on individual assignments and higher letter grades at the end of the academic year are more objective measurements as they are based on concrete academic performance and outcomes.
