r u giving the exams in the Nov 2010 session?? If so, they r there in the syllabus..........
u never know....they might come too!!

but they r too easy in the electricity part!! Don't u think so??

Simply remember their structure.....and then they are easy to work on!!

An easy way to memorise the Truth Tables is like this :

For AND always multiply the inputs to get the output e.g.   Input A = 1 Input B = 0 So output = 1x0 = 0

For OR always add the inputs to get the output e.g.   Input A = 1 Input B = 0 So output = 1+0 = 1

For NOR just write the opposite of the given input e.g.  Input A = 1 so output = 0

They ARE after all in the syllabus, but if I can hazard a guess based on the May/June 2010 papers, I doubt it'll come out. Focus more on the basics like Pressure, Force and etc.
