Comprehensive Exams
for students choosing the Non-Thesis Option in the M.S. Program in Computer Science
Fall Semester '97

To:
M.S. Students in Computer Science Studying at the Coral Gables Campus
From:
Comprehensive Examinations Committee
Date:
October 11, 1996

Objective

Comprehensive exams will test general knowledge in computer science -- the knowledge every computer scientist is expected to possess. The questions in the comprehensive exams will concern important ideas, not technical details. Although certain computer science courses are recommended as helpful in preparing for the comprehensive exams, the questions asked will differ in character from the questions from corresponding final exams. An old proverb says "one cannot see the forest for the trees"; in a comprehensive exam the students are expected to show that this is not the case for their understanding of computer science.

Students can prepare for comprehensive exams by taking courses and/or by individual study. Normal course selection will prepare the student adequately for the Core Comprehensive Exam. However the student must be careful to select appropriate courses to prepare for the Advanced Comprehensive Exams. Course sequences are highly recommended to establish the concentration required for success in the Advanced Exams.

Requirements

A student who chooses the Non-Thesis Option is required to pass the the Core Comprehensive Exam and two Advanced Comprehensive Exams.

The Core Comprehensive Exam covers the material required for a B.S. in Computer Science and additional topics specified by the Curriculum Committee. These topics are essential to every computer scientist, independently of the specialization.

Each Advanced Comprehensive Exam corresponds to a possible specialization offered by the department's computer science curriculum at the M.S. level. The Advanced Comprehensive Exams must be chosen from the list prepared for the given semester by the Curriculum Committee.

Detailed list of topics for the Core Exam is available. (The list may undergo slight adjustments from one semester to another, so please make sure that you are using the current list.) The list includes references to literature. The books which are quoted are not required, there are other sources of the same information.

It is not necessary to pass an examination at the first attempt. Nor is it necessary to take the exams in the same semester. (The Comprehensive Exams are offered once in the fall semester and once on the spring semester.)

Advanced Exams

Schedule

Students intending to take the Core Exam or any of the Advanced Exams must inform the Department of Mathematics and Computer Science in writing before November 6, 1996. Please specify which Advanced Exams you intend to take.
