Know what you're doing !
Go through how to do it and do a few practise questions.
Go through how to do it and do a few practise questions.
Learn how to convert to binary with the most emphasis, then convert freely from binary to either octal or hexadecimal by grouping,
ie. 493 == 111101101 (base 2)
111 101 101 == 755 (base 8)
1 1110 1101 == 1ED (base 16)
This is how I did every conversion when I did 2/3U CS in the 97 HSC.

i would guess, if u want to convert dec to bin, you do this:
say 493: divide by 2. If there's a remainder, the last digit is 1. Otherwise it is 0. Get the whole number quotient (i.e. 493/2 = 246 + remainder, 246 is the quotient), and do it again. 246 has no remainder, so the next digit (the 2nd last) is 0. get 246/2 = 123, do it again, etc.
There must be a quicker way, but *shrug*

U can do it on most calculators too. Just change to base mode and u can input convert between bin, dec, hex etc.

I think you're right. Just noticed it on the equipment list. We've always been able to use it in the trials and other assessments tho. Better start learning them then.
