Great course. There is a lot of content covered. It is very informative and interesting. Sophia learning coaches were always great about answering any questions I had and got back with me very quickly. I used the Sophia written tutorials in this course. I did not use the instructors in this course, because their teaching styles did not help me. I was excited to finish the course today with the ID verification milestone. I am ready to move on to another course! 🙂 Thanks Sophia for another great course!!

I love Sophia's learning coaches. They are so informative, helpful, kind and so quick to respond. I would recommend Sophia to everybody that has pre-requisites to complete!

Hard, but very good. I really like the teachers and the way it is set up.
by Brandon W. on June 15, 2017
Some of the questions were somewhat confusing and the answers were too similar for some questions.
Sophia replied on June 15, 2017

Hi Brandon— Congratulations on your successful course completion! We appreciate your feedback about the question and answer choices, and will certainly take it into consideration as we continuously work to improve the student experience. In the future, please feel free to reach out to our Learning Coach team before your final test if you ever need assistance with a question or concept!

Some questions are debatable and some answers are unclear. This has occurred a lot among my classmates and I, and the videos need to be more direct as to what the correct answer for a specific situation is.
Sophia replied on June 15, 2017

Hi Madison— Congratulations on your successful course completion! While the tutorials are designed to provide all the information necessary to answer the assessment questions, our Learning Coach team is here to assist you if you ever need further clarification about a question or concept presented in the course. Congratulations again on completing the course and earning these college credits!

Great course with a LOT of information, seems like each unit could have been a course in itself. The ID verification test was the hardest of all I've taken, study for it!
by Dana K. on June 7, 2017
Tons of information, very stressful but able to complete and get a B in the course I am very satisfied overall.
Sophia replied on June 8, 2017

Hi Dana— Congratulations on your successful course completion! Yes, this is a challenging college-level course, so there is a substantial amount of material covered. However, the course is pass/fail, so no letter grade is awarded. Additionally, the Learning Coach team is here to help you with any questions you may have. Congratulations again on earning these credits!

My first online course - certainly not easy, but I think the elements of teaching and learning are appropriate.


  • Q: Does Sophia accept third-party payment for tuition, such as financial aid or military benefits?
    A: Sophia courses are not eligible for most third party payment methods, and must be paid for by credit or debit card. Tuition is due at the time of course registration. Sophia offers both full and partial payment plans as part of the registration process.
  • Q: When do the courses start and how long do I have to complete a course?
    A: You choose your own start date and have 60 days to complete each course. However, because the courses are self-paced, you can complete them in fewer than 60 days.
  • Q: Where do I get the textbooks for my course?
    A: You do not need any textbooks for Sophia courses. All material is taught by video and text-based tutorials that are in the course room, and are included in the cost.
  • Q: How am I graded in the course?
    A: Your overall score is derived from how you do on two types of assessments: Challenges, which are formative assessments, and Milestones, which are summative assessments. Sophia’s English Composition I, Foundations of English Composition, and Public Speaking courses also include written assignments, called Touchstones, that also contribute to your overall score.
  • Q: How do I know which courses I should take?
    A: Consult with your academic adviser at your university to determine specifically which Sophia courses could fit into your program. You can download the course syllabus directly from our site to share with your school advisor.

Oh no. Please don't go.
