While a bachelor's degree in computer science is an excellent way to gain a solid foundation in the field, a master's degree in computer science can lead to greater career potential and higher-paying careers. Many students who enter the bachelor's program continue their studies into the Master of Science in Computer Science program. This is why National University offers a bachelor's to master's degree transition program. The goal is to make the transition to the master's program seamless and efficient, so you waste no time in between programs. The number of courses required to earn an MSCS degree for transition program students is reduced from 12 to as few as 10 courses, so you can finish your master's degree faster.Students must complete graduate-level coursework taken as part of the BSCS degree with a grade of “B” or better. This coursework, which counts as electives, will not transfer as graduate- level credit to National University or any other institution as it is part of an undergraduate degree program. Grades earned in graduate-level courses will be calculated as part of the student's undergraduate grade point average. Students must be within completing their last six courses in their undergraduate program and have a cumulative GPA of at least a 3.0 to be eligible. Lastly, students must apply for and begin the MSCS program within six months of completing their final BSCS course. Students must complete their MSCS program within four years, with no break exceeding 12 months. Students in the BSCS transition program may take up to two MSCS classes as electives during the BSCS. Students may choose from the following courses: CSC 603, CSC 605, CSC 675, CSC606, and CSC607.
