How to study this course (similar to MAE 335) 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 2

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. 3
