Exam tips Read the question!!!! What are you being asked for? How many options do you have to choose Each question is on its own, does not relate to previous questions On code segments, play spot the difference Check the parameters and logic. Don’t assume Know when to use particular classes Finally, if it is old tech vs new, new is probably the answer 

What are you being asked for?

How many options do you have to choose

Each question is on its own, does not relate to previous questions

On code segments, play spot the difference

Check the parameters and logic. Don’t assume

Know when to use particular classes

Finally, if it is old tech vs new, new is probably the answer 
