IMPORTANT ALERT FOR Computer Science M/J exams!!!

I dont actually know whats coming for the exams, but heres some stuff that hasnt showed up for the past few years that is in our syllabus:

the analysis part of the PDLC features : structure diagrams, flowchars and psuedocode

Validation is: double entry and visual check

Types of test data is: arithmetic, boolean and logical

Creating a maintainable program involves: using validation checks, iteration and sequence

MOD is when you remove the fractional part of a quotient (the resultant of multiplciation) and DIV is when it returns the remainder after a division

XOR returns true when both values are false and NOR returns true if only one value is true

Make sure you know about the XNOR logic gate, in came up in feb march according to my friend and no one knew about it

Im wishing you guys luck for the exams!!! I know we can all get A*/9s together!
