  • Emma Abbott completed this course, spending 10 hours a week on it and found the course difficulty to be hard.

    This course is college level - students will need to have a good background in algebra to get the best out of this one. I found the notation for entering equations a bit of a challenge to get my head around, if you are even one digit off it will mark you wrong. The lecture videos are good though, quite engaging even with a bit of So-Cal accent:)
