Practice Set 1 AP CSP Written Response 1

StudySessionTimer — Program Purpose

Sample program: StudySessionTimer helps a student decide how long their next study session should be, based on a stored list of their past session lengths (in minutes). Read the program description, then write Written Response 1.

What to write

Name the program and state what it does in one or two sentences.
Explain the program's purpose — what need or interest it addresses.
Describe a specific input and the resulting output, and explain how that input/output pair demonstrates the program working correctly.

Starter shape

PROGRAM: StudySessionTimer

Purpose: The program helps a student build a sustainable study habit by
recommending how long their next study session should be, based on the
lengths of their past sessions.

Input: sessionLengths, a list of numbers representing the length (in
minutes) of each past study session the student has logged.

Output: a single recommended number of minutes for the next session,
displayed to the student.

Key procedure: getRecommendedLength(sessionList) — takes a list of past
session lengths and returns a recommended length, capped between 15 and
90 minutes.

======================================================================
Write Response 1 below.

Prompt: Describe the overall purpose of the program you are submitting
for the Create performance task. In your response you must:
- Name the program and describe what it does.
- Explain the program's purpose, including the need it addresses or
  the interest it explores.
- Describe what the input(s) and output(s) shown in a run of the
  program demonstrate about its function.

Common traps

Describing what the program does technically (loops, lists) instead of its purpose for a real user.
Giving a vague input/output example ("the user enters numbers and gets a result") instead of concrete values.
Never connecting the example back to why it proves the program works.
Restating the prompt instead of answering it in the student's own words.
