All the best to everyone who is appearing for ON 2012 examinations.....Everyone should get an A*
same 2 u but i had a doubt that even if some keywords are missing from the answer but the explanation gives what it wants from keywords so do they give marks or not??
in ict theory is it okay to write each answer in bullet points??

For ICT theory u cannot write it in bullets it will not earn u marks even if it is completely correct.
Key words are important as they dont have an alternative. Like for example Define diffusion: U ll have to say down a conc gradient.....u cannot say from more to less u gettin meh...????
