PLS 120 - Animal Science Laboratory
| Note: Laboratory exercises are due at the beginning of the laboratory period the week after they are assigned. Exercises will be graded and returned. The answers to the exercises will be posted on this web page. Late exercises will be accepted no later than Friday of the week when they are due, and 5 points will be deducted from the grade. The laboratory grade is worth 25 points of your final course grade. If you turn in all the exercises and achieve an average grade of 80% or better in the lab, you will receive the 25 pts. Otherwise, your course points will be prorated in relation to your lab average. For example, if your lab average is 50%, you will receive 12.5 pts. towards your course grade. |
