Cheating is out of question, invigilators here are crazy! I was withheld for 10 mins after exam just because one of my friends looked at me when the papers were being collected! And i wasn't the culprit at all!
And it would be good managerial test for me!

hmm... fortunately for me, i got a very bonga invigilating staff!! i was able to tell my friend who was sitting in front of me, one complete answer about the systems life cycle! though will not do it again ever!! maut ho sakti hai!

got notes about CRO, semiconductor, potential divider,bistable&astable circuit? im not sure about the function and the structure like why that thing put at there and it put there for what and something like that...
and i wanna ask:
1)convection can only occur in liquid and gases?
2)how heat energy transfer into and out of a house?
3)we have to memorise the colour of resistor? or the information will be given?

actually, the colours are given, though you must know which band stands for what!

8.B
if the vertical line of force of gravity is drawn from C, it is about to move out of the base of the bus. if we tilt a little more, it will topple so it cant be C .

Can u tell me how did u draw this line ?

yar simply, draw a line from C vertically down to the ground and see if it lies inside the base area or not.
if it does then it is the centre of mass.

Mcq 8

It's C because the bus stands on its tyres, draw vertical lines from each point and see which line just touches its left tyre. The line you draw is the line of action of weight of the bus. This determines whether the bus will topple over or not

also can someone explain the MCQ 9?

Is the Answer D

How can you get confidence to even show your friend the answer? Its CIE boss! Not any regular school exam.
Just thinking of it gives me the shivers!
