Format One question per topic discussed above. Each question may have subsections No programming: but pseudo code may be required Given a piece of code you will identify the purpose Use diagrams/figures where ever possible 6/16/2025 B.Ramamurthy 4
How to study? Prepare? Come prepared: there is no substitute for hard work View the videos and follow class handouts Review class notes; Understand project work and class work Find ways to efficiently answer questions Find ways to avoid silly mistakes Create 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 questions Build up competencies as you are reviewing the course material and not deficiencies Good luck. 6/16/2025 B.Ramamurthy 5
