What Are My Choices
If I Already Have a B.S. Degree???
• A Bachelor’s Degree in Computer Science
– may be quicker for some students
– allows for modest performance
– broader topical coverage by design
• A Master’s Degree in Computer Science
– may be quicker for some students
– requires superior performance
– more focused study (but can follow a broad
curriculum if you want)
What Are My Choices
If I Already Have a B.S. Degree???
• A Bachelor’s Degree in Computer Science
– must complete all undergraduate major UG
requirements besides just CS courses
– Comm 220 (Public Speaking); Wr 227 (Technical
Writing); Mth 251, 252, 253 (Calculus I, II, III);
Approved Lab Science; ECE 341 (Computer
Hardware); Stat 451 (Applied Statistics for
Engineers and Scientists); Approved mathematics
electives; Approved science electives

• Not a vocational training program
The New Beginnings Option
an alternate to the Grad Prep Program
• Admission to New Beginnings is competitive
• Applicants are expected to have at least a year
of mathematics beyond pre-calculus (Calculus,
Linear Algebra, etc.)
• An undergraduate GPA of 3.5 or better

• Nine additional graduate level CS courses
A Couple of Things to Keep in Mind
• Advanced courses in Computer Science build
on earlier courses.
• It isn’t just about checking off courses – a
weak preparation in one class may mean
problems throughout the rest of your
program.
• We enforce prerequisites! If you haven’t had
the class, or done a CPL, you’ll be barred from
registering for advanced courses.
Entry Points to the Program
• No prior programming experience
– Start with CS161
• Programming experience
– Start with CS162
• Self-placement into CS162:
• Write a function that receives two parameters: an array
(or list) of integers and an integer value indicating the
number of elements in the array. Each element in the
array will be either a 0 (zero) or a 1 (one). The function
should count the number of zeros and the number of
ones in the array and return the larger of the two counts.
I Took My CS Classes a Long Time Ago
• Once again, it isn’t just about checking off
courses – a weak preparation in one class may
mean problems throughout the rest of your
program.
• If you can’t recall what you covered in a course,
or do the problems without peeking, you
probably need to retake it.
• What about self-study? It works for some people,
but not most, or even many. If it’s been a long
time, and you decide to “brush up” – cap it off
with a CPL to evaluate if you really did.
Scheduling
• Once again, we enforce prerequisites. Make sure
you take them into account when planning out your
program.
• Our admissions (to the upper division CS program) is
in the Fall (July 1 deadline) and Spring (February 1
deadline). Students begin with CS300 and CS311
which are only offered in the Fall and Spring.
• All your lower division CS should be complete by the
time you are admitted and take CS300 and CS311.
What’s This Admission Stuff?
• Once students have mastered all the lower division
course work, as documented by course grades or
CPL, they can apply to the CS major (or in the case of
postbacs, the grad prep program).
• This allows us to assume a certain minimum level of
skill and knowledge among students in the upper
division courses.
• You will not be allowed to register for upper division
courses unless you have been admitted to the
program
What Do I Need In Order to be
Admitted to the Grad Prep Program?
• CS Courses: CS162, CS163, CS201, CS202, CS250,
CS251 with a 3.0 GPA over all attempts at these
courses.
• To have a chance of getting admitted to the graduate
program, you really need to complete all these
courses with a minimum of a B, and have NO retakes
within the past few years.
• If you did not take CS202 at PSU, you’ll also need to
demonstrate that you have gained an acceptable
level of proficiency in programming in one of our
scheduled Proficiency Demonstrations.
Very Important
• You’ll need to get As and Bs (mostly As) in all
the preparatory CS coursework you take.
• Anything below a B- at the graduate level is
considered failing, so if you’re getting C’s or
even too many Bs, you won’t be a candidate
for the graduate program.
• And yes, if you repeat a class, the Admissions
Committee considers all your attempts.
What Do I Need In Order to be
Admitted to the Undergrad Program?
• CS Courses: CS162, CS163, CS201, CS202, CS250,
CS251 with grades of C PLUS a 2.0 GPA over all
attempts at these courses.
• Mth251, Mth252 (Calculus I and II)
• An approved Lab Science sequence
• COMM 220
• Demonstrate that you have gained an acceptable
level of proficiency in programming in one of our
scheduled Proficiency Demonstrations. If you take
CS202 at PSU, that is part of the Final Evaluation.
Using Credits From
Your First Degree Program
• Chances are you have taken some (perhaps
many) of our required undergraduate courses,
especially Math and Science.
• See transferology.com to determine if your old
courses will match one of our required courses:
– https://transferology.com/school/pdx
– If your school is not in transferology, you’ll need to
contact the course’s home department here at PSU
and see if your course is equivalent to the one taught
here.
– Make sure you have your syllabus, samples of your
exams/homework and the course appears on your
DARS Report.
I Have Lots of Experience
• There are some courses you can waive on the
basis of documented professional experience.
• WR227 (Technical Writing) and/or COM220
(Public Speaking) can be waived if you can
provide us with materials documenting your
experience writing and/or giving
presentations at work. We will evaluate these
materials based on our expectations of what
we expect of our students from these classes.
We won’t waive these courses for writing
reports or giving talks in courses at school.
I’ve Taken Other CS Courses
Elsewhere - What About Those?
• If the course is in transferology, you can transfer
it to replace the corresponding PSU CS course.
• If the course isn’t in transferology, you’ll need to
take a Credit for Prior Learning (CPL) to
demonstrate that you have gained (and retain)
the knowledge and skills that go with that course.
• CPL is available for all of our 100- and 200-level
CS major courses.
