data warehousing and SQL programming. The four core required data mining courses are
designed to be taken sequentially and must be taken in the order shown on the course matrix.
Can the statistics prerequisite be waived if I have taken a statistics course
elsewhere or have equivalent working knowledge?
If you already have a solid foundation in statistical methods and feel comfortable with your
level of knowledge to move directly into Data Mining I, then you can skip statistics without a
waiver.
* Attached is a short self-assessment quiz to help you gauge whether or not
you should skip the “Introduction to Statistics” prerequisite.

followed by enrolling in the individual courses as they are offered.
What kind of credit do I earn? Is it accepted at other universities?
You will earn Continuing Education Units (CEU). The CEU is a uniform measure of non-credit continuing
education learning experiences (no academic units are involved). One CEU is defined as ten contact
hours of participation in a continuing education course. Employers, professional groups, licensing
agencies and others who routinely examine and evaluate individual accomplishments generally accept
this unit of measure.
Each individual academic institution decides whether or not to accept UCSD Extension’s CEUs. If
you wish to transfer credit, it is your responsibility to confer with the receiving institution's advisor
before enrolling.

3. How can I get more information on the specific courses?
Please email unex-techdata@ucsd.edu to request for specific syllabi.
What are my grading options for each course?
If you plan to obtain a certificate, all courses must be taken for either a Letter Grade or Pass/No Pass.
You must earn a grade of at least a "C-" or “Pass” in order to apply the associated units towards the
certificate. A "Pass" grade is equivalent to a "C-" or better.
How will I receive my final grade?
Once the course is completed, the instructor has 10 working days to submit your grades. After
the grades have been posted, you can view and print them via My Extension, your online
education management portal. Please contact Student Services at 858-534-3400 or unex-
reg@ucsd.edu if you experience any issues with logging in.
How long is each course?
Each course can vary; they generally run from 6 to 9 weeks.
Can I enroll in more than one course per quarter?
The required courses should be taken sequentially as each course builds on its predecessor. However,
you can concurrently enroll in one of the required sequenced courses and an elective course. Please
contact unex-techdata@ucsd.edu for exceptions.
Can I get a copy of my receipt?
Yes, please login to the My Extension website and select ‘Documents’ as the top of the page.
Please contact Student Services at 858-534-3400 or unex-reg@ucsd.edu if you experience any
issues with logging in.
How are the online classes formatted?
The online courses are asynchronous. They have a start and end date but all the lessons are
uploaded on Blackboard, our online learning management system, so that you can learn at your own
pace. However, please be aware that you may have weekly assignments, quizzes and/or tests that are
due on specific dates. Please click here to take a sample course tour to see if this format suits your
learning style (click on the link in the upper right-hand corner).
Once I have enrolled in a course, when will I get online access to it?
If you have enrolled at least 3 days before the course begins, generally you will have access starting on
the first day of class. You should receive an email from Student Services with instructions on how to log
in to the course. If you have enrolled on or after the start date of the course, you will have access within
24 hours.
How do I communicate with the instructor(s) if I have a question or need feedback?
Each instructor has his/her own preferred method of communication and response policy. However, most
instructors utilize email or the discussion board and will respond within 24 - 48 hours.

4. How many hours can I expect to spend studying outside of class time?
Each student has their own learning style so this can vary greatly. As a rule of thumb, expect to
spend an average of 2 hours studying for every hour you spend “in-class”.
Will I get any hands-on experience in the program?
Most courses combine theory with hands-on exercises.
What tools are used and what are the system requirements?
WEKA 3.6 (or higher), an open source tool readily available for download, is predominantly used in
all required courses. Please click here to review the installation procedure.
Would I be able to order the required text books before the class begins?
Yes, you can order the book(s) at any time from retailers such as Amazon if the instructors post the text
requirements/recommendations on their associated course enrollment page.
What are the instructors’ credentials?
All the instructors have a graduate level degree and at least 10 years of practical experience in
the industry.
