• 完成专项课程需要多长时间？

  Each of the six courses is scheduled for 4 weeks, with a typical week requiring approximately 5 hours of work (reading, videos, quizzes, and projects). If you work steadily, you should be able to complete the Specialization in 24 weeks, with a total of approximately 120 hours of work.

• What background knowledge is necessary?

  This specialization is designed to be accessible to students who have taken typical college first-year (freshman) engineering courses. The student should have an understanding of:

  Freshman-level physics, including f = ma; masses, springs, and dampers; vector forces; and vector torques (or moments) as the cross product of a distance vector and a force;

  Linear algebra, including matrix operations, positive definiteness of a matrix, determinants, complex numbers, eigenvalues, and eigenvectors;

  Some calculus, derivatives, and partial derivatives;

  Basic linear ordinary differential equations; and

  A little bit of programming experience.

• Do I need to take the courses in a specific order?

  It is highly recommended you follow the courses in the specified order, since the material builds on itself throughout the Specialization.
