Frequently Asked Questions

This page answers some questions that we frequently receive about the curriculum. If you have questions that aren't answered here, try asking through one of our community channels. If it seems important enough or we get asked that question a lot, we will probably add it here.

Alternatively, you could contribute an answer yourself.

Questions

How can I review the math prerequisites?

Many OSSU students choose to review math topics that they have not studied recently. OSSU recommends students use Khan Academy for such a review. Below are links to topic assessments. After taking an assessment, you should have a clear idea what topics to study, and resources on Khan Academy to use.

(Math 1, 2, 3 covers all of algebra, pre-calculus, high school geometry, trig, stats. It interleaves the order of these topics.)

In what order should I take the courses?

You have a few different options:

  • You can progress linearly from top to bottom of the page.
  • You can progress linearly through each individual section, but studying different sections in parallel.
  • You can design your own custom progression using the pre-requisites to guide you.

We have designed the curriculum to work for any of the above three styles.

Does every resource in the main curriculum have to be free?

Yes, that is a core goal of OSSU.

At the same time, we recognize that education is a resource that requires payment to instructors to make it sustainable in the long term. Therefore, we respect the business model of websites like edX, which make their materials free but with some paid add-ons, like official certificates or extra interaction with course instructors.

So we only require that the learning materials of a resource be free to access, not that every possible add-on be free. It would be ideal if graded assignments were always free. In the event that free assessments are not available OSSU looks for alternate assessments to pair with a course.

Are Coursera courses free to access?

Some courses that require payment to access probably do exist on Coursera, but we don't put those on our curriculum. All Coursera courses that we put on the curriculum must, at minimum, be free to audit. For some courses, all course features are available for free; for others (especially those that are part of a specialization), you may only be able to access the lecture videos. (If you find the policies have changed for any courses on our curriculum, please tell us!)

Unfortunately, for some courses, Coursera's interface is very aggressive about convincing you that you have to pay.

You may see something like this on the course page:

Free Trial

When attempting to enroll in such a course:

  • Click the blue "Enroll" or "Enroll Now" button.
  • A pop-up will appear.
  • Do not click "Start Free Trial", unless you do want to pay.
  • Find the text that says "Audit this course" at the bottom.
  • Click Audit.

Is it necessary to purchase the Verified Upgrade for edX courses?

If you just want to watch the videos, it is never necessary for any edX course on our curriculum. Note that a number of edX courses only allow students to audit a course for the estimated number of weeks it takes to complete. Students should not begin a course until they are prepared to focus and complete the course.

Why doesn't the curriculum cover/ignore topic X?

You can read more about our curricular guidelines and the qualifications of the guidelines' authors here. If you find a topic that is required by our guidelines and is not included in the curriculum, we should make a change! Read more about contributing to a change.

Why is the curriculum missing some pre-requisites?

The curriculum assumes two things:

  • You are reasonably fluent in English.
  • You have gotten through a standard high school curriculum that included physics and pre-calculus.

Without these assumptions, the curriculum would be out of control with trying to fill in your knowledge gaps. For those who want to study math pre-requisites, read more here

Of course, if you find that the curriculum is missing a pre-requisite for a course that isn't part of a normal high school curriculum, please let us know!
