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.
