Program Specifications Write a program to calculate a course grade given points for homework, quizzes, midterm exam, and final exam. Grades are calculated differently for undergrads, grads and distance learners.Note: this program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress.Step 1 (2 pts). Read from input student status (String), homework points, quiz points, midterm exam score, and final exam score (double). Valid student status includes undergrad (UG), grad (G), and distance leaner (DL). Calculate each category average using maximum points for homework (800), quizzes (400), midterm exam (150), and final exam (200).

Submit for grading to confirm two tests pass.Ex: If the…
