What are the differences between required, elective, and optional courses in a career track?

Career tracks give you the opportunity to experience a new way of learning. They build the right skills to excel in a specific data science role. Every career track consists of 7 required courses, 2 electives, and 1 optional course. They are organized in a logical sequence, with each course building on what you have learned from the previous one.  

Required courses – There are 7 required courses in a career track. Whether or not you watch all video lessons in a required course, you must pass the relevant course exam to proceed with taking the final exam. We give you the chance to complete these courses at your own pace, in any order you prefer.  

Electives – There is a dropdown menu where you must choose 2 electives in each career track. Whether or not you watch all video lessons in an elective, you must pass the relevant course exam to proceed with taking the final exam. Again, we give you the chance to complete these courses at your own pace, in any order you prefer.  

Optional courses – There is 1 optional course at the beginning of every career track. Completing an optional course exam is not a prerequisite for taking a final exam, neither does it play a part in the overall exam criteria. It is simply a way for you to gain additional knowledge at your discretion. Note that you are still eligible for a Course Certificate once you pass an optional course exam.  

Since everyone joins our program at different proficiency levels, you can take the career track courses in any order you like! You don’t have to complete a preceding course to unlock the following. We strongly recommend that you watch all video lessons included in a career track. However, those of you who feel they have sufficient knowledge of the topics covered in a course can directly proceed to the course exam without watching all the videos. Whether you fail or pass on your first attempt, you must watch at least 30 minutes of the course content every time you wish to retake a course exam.
