How to study this course (similar to MAE335)
  • Before Class
  • Read (at least look at) assigned sections
  • In Class
  • Do not try to take detailed notes
  • Listen to, fill in, and understand what you have
    read
  • Write down key words for concepts, definitions,
    problem solving techniques, etc. so you know what
    to emphasize when reading the book.
  • Ask questions

How to study this course
  • After Class
  • Study key concepts write out definitions and
    descriptions
  • Work assigned problems simultaneously study
    theory and example solutions
  • Go to recitations only after you have tried to
    work the problems yourself. The TA will only give
    you hints when you are lost they will not solve
    the homework problems for you. The TA may provide
    additional examples.
