Essay type questionnaire and Yes/No questions, the method is constrained to find solutions. We also discuss dependable factors and its percentage affecting for different questionnaire. The Cronbach’s alpha value is high for descriptive type questionnaire rather than MCQ, which show internal consistency, is high for descriptive type. T-test is conducted for the variation from one type questionnaire with combination type questionnaire. Current evaluation method does not fulfill the actual goals and this will lead to even misleading the assessment criteria rather than what they gained.
