TUTORIAL 2
NERVOUS SYSTEM I

Student’s Guide:
At university level, the tutor facilitates student learning without spoon-feeding. Therefore, you are expected to:

* Read your textbook, attempt the questions before the tutorial
* You may enter the class and sign your attendance after showing your tutor that all tutorial questions have been completed; even if you don’t know how to do, write something - you’re not advised to leave answers blank in the finals.
* Write answers on board if you wish to receive tutor feedback
(no answer, no feedback)
* Be independent: consult textbooks or dictionaries on your own first before asking the tutor
* All questions are compulsory. 1 mark may reflect 1 answer point.
(No half mark is awarded in the finals marks)
