FormatOne question per topic discussed above.Each question may have subsectionsNo programming: but pseudo code may be requiredGiven a piece of code you will identify the purposeUse diagrams where ever possible
How to study? Prepare?Come prepared: there is no substitute for hard work Review class notes; Understand project work and class workFind ways to efficiently answer questionsFind ways to avoid silly mistakesCreate a mental checklist to make sure you have not missed anything important on the exam (like your name of the exam paper!)Read the question paper and strategize on the order in which you will answer the questionsBuild up competencies as you are reviewing the course material and not deficiencies…Good luck.
