i think we had to multiply by 2 coz it sed that sampling needed to be done for both the right and left speakerswasn't the no of Mb's for the music track 15.1 how can it be 30.1 and why are we multiplying with 2 as it is not a cassette player

To clear anyone doubts:
JUST ASK THE QUESTIONS AND I WILL ANSWER IT!
(hoping that the answers are good)
>flowchart output = 5
>Logic Gates : starts with 1 and end with 0 (do not remember it)
>MP3 = was like something with 30 minutes (first answer was 17k)
Remember that the music should be sampled two times for the right and left.!
(Damn, you were blind while reading those 3 phrases written on purpose)
>Algorithm
1.
greater1000=0, less1000=0
for i=1 to #
Let X input number i
if X < 1000 then
less1000= less1000 + 1
else if X >1000 then
greater1000= greater1000+1
else if X= -1 then
i=#
end if
Next
Output greater1000,less1000
2.
palin=0
for i=1 to 50
Let D1 input the first number i
Let D2 input the second number i
Let D3 input the third number i
Let D4 input the forth number i
If D1=D4 AND D2=D3 then
palin=palin+1
end if
Next
Output ((palin/50)*100)

I really think your last algorithm is correct. I had a lot of difficulty with it. I just hope everything worked out

Well,it seems right to me. At least there is some logic to it.

Bit streaming:
-Send of data slow, part by part, and it can be read even if not completely downloaded.
-Used in printer(buffer)
Mp3: about 30-32 (don't remember clearly)
Quality:
While converting into Mp3 the spaces that are not need are cleared up to reduce its size.
Only the sound is kept.
Pixels:
1. Not the adequate number of pixels
2. Monitor

I though, realise that this paper was one of the most challenging of all.Don't worry. Cambridge will surely lower the marks for getting an A* as this was one one the hardest paper ever created
But, unfortunately, Cambridge will not lower the gradings!
More capable pupils were able to complete the paper with only 2/3 errors!
And i did the paper like it was so easy to me!
Algorithms were the most challenging but, i did everything else without even being overpowered by Cambridge!
I lost around 10-12 marks.I will be taking Paper 32 by the way.Do you think an A* is still achievable ?

Yeah, never mind, whatever results you are going to have!
HSC is another and last chance for you to prove your real power!
Don't blame yourself for that!
Believe in you and catch up in paper 32 !
I am with you!
Akr!...

of course school is not cambridge but every year cambridge changes the grade to get A*. at school the teachers try to give the least possible marks for u to work harder!!!Never did this at school!
for e.g. the grade to get A* for physics was 75 in the year 2010 and 85 in 2011
