Student Test Analysis

This document describes a three-part FOCAL 4K program designed to score and analyze student exam results.

• Part I scores individual exam sections, outputting student scores and the percentage of the class that answered correctly.
• Part II calculates and prints overall student scores, class mean, standard deviation, and a decile distribution plot.
• Part III provides detailed item analysis, calculating the distribution of student responses for each question as a percentage of the class.

The program uses punched paper tape for data input, following a specific format for answer keys and student responses. Due to the program's division into three parts to manage memory, the documentation includes a specific set of memory patches to prevent input buffer overflow.
