During the actual exam, does check boxes signifies there is more than one answer?

[Frankie Chee]

Hi all,
I have a few doubts about SCJP exam would appreciate if someone who have gone through the actual exam would help me.
Sure this would be helpful to others who are taking the exam for the first time!
I understand that during the SCJP exam, if I am given possible answers with radio buttons, I know it there can be only one possible answer for that question. What if it comes with checkboxes, this allows me to select more than one answer for that question and does that necessarily means that those questions with checkboxes will definitely have more than one answer? Or can there be only one correct answer?
Secondly during the actual SCJP exam, will I be given hints on how many correct answer for that question? I read from somewhere we would be given "hints", If so, how will they "hint"?

the questions will specifically say "Choose the 4 correct answers" or "Choose the 1 correct answer" -- the test even goes so far as to give you an error message if you select too many or too few answers.
So no worries about that -- you'll always know how many answers you need to pick, and remember there's no partial credit -- you have to get all the answers correct for a particular question or you don't get the point.
Good luck!

Dear Colin,
It makes life easier but I'll strongly advice you to "Not Guess" based on the "Number of possible correct answers note" while practice through mock exams. In case you make a guess, make it a point that you revise the question even if you do it right. Many times, our guess clicks and we forget to verify the answer and explanation.
I hope this adds some value.
Best wishes,
Pradeep

Jess:
does that means that the exam will tell me how many answers there are for every single question?
Secondly, do in the exam do I have to know how to convert Hexadecimal to numbers?
If not any idea where I can find online tutorial on this?

does that means that the exam will tell me how many answers there are for every single question?
yes -- every single question will tell you how many answers.
Secondly, do in the exam do I have to know how to convert Hexadecimal to numbers?
Honestly I don't remember. Its been asked a bunch in this forum so do a search for something like 'convert Hexadecimal' and see what you can find.

Converting Hexadecimal to Numbers
Lets take a simple hexadecimal number 0X0012
Decimal equivalent would be
0*16 to the power of 3 (total count in the number -1)
+
0*16 to the power of 2 (total count in the number -2)
+
1*16 to the power of 1 (total count in the number -3)
+
2*16 to the power of 0 (total count in the number -4)
=
0+0+16+2=18
Otherway of calculating would be represent each digit in the hexadecimal number to corresponding binary of lenght 4
so 0012 becomes 0000 0000 0001 0010
Assume a hexadecimal number 0X2345
To get to the corresponding decimal number you have to do the following calculation
2*16 to the power of 3 (total count in the number -1)
+
3*16 to the power of 2 (total count in the number -2)
+
4*16 to the power of 1 (total count in the number -3)
+
5*16 to the power of 0 (total count in the number -4)
In otherway 2345 would be 0010 0011 0100 0101
Naturally this would be a big number
