Midterm test

The midterm test will be held on Saturday, March 9th, 2019 at 2:00 pm. You will write the midterm in ETLC E1-013 (Section EU1) or ETLC E1-017 (Section EV1).

Some details about the midterm:

  • Duration: 90 minutes.
  • Material covered: Up to, and including, power series solutions of linear differential equations, i.e., Chapters I to IV in class.
  • Some questions may be multiple choice.
  • NO calculators, formula sheets etc.!
  • NO cell-phones, i-pods, or other electronics!
  • Please bring a valid ID with you.
  • Several MATH 201 midterms from previous years have been posted on eClass. Please look at them carefully.
  • Good luck!

The Decima Robinson Support Centre in CAB 528 is welcoming MATH 201 students preparing for the midterm; see here for details.

Two MATH 201 review sessions will be held by retired math professor Dr. Allegretto on Tuesday and Thursday (March 5 and 7) at 5:00-6:30pm in ETLC E1-001. This is an excellent opportunity to get your last-minute questions answered, so you should make an effort to attend.

Midterm test average: 75.65%

Solutions have been posted on eClass.

Final exam

The final exam will be held on Friday, April 12th, 2019. More information regarding the final will be provided later, both in class and on this website.

Other material

A free textbook that covers the material of MATH 201 (and much more) is W.F. Trench, Elementary Differential Equations with Boundary Value Problems; it contains LOTS of practice problems and is available here.

Need help? The Decima Robinson Support Centre in CAB 528 offers free drop-in help sessions, Monday to Friday, 9:00 am to 3:00 pm. It's a great, friendly place, though quite busy at times.
