Rounding for Math problems on NAPLEX

[STAR3URY]

Hey guys quick question...I am kind of confused on the rounding for the NAPLEX choices. I know that the problem will state to round to the nearest tenths, hundredths, etc. My question is during multiplication or division how do we round because some people may use the actual number to perform the equation and some people may round to the nearest hundredths to perfrom the equation and then we can come up with a different answer (off by 0.01-0.05) but since the naplex has fill ins wouldn't that mark the answer wrong? or do the fill ins work on a range basis, where your answer has to be within the range?



Can someone please clear this up? I hope that wasn't confusing.

I got a question wrong on rxprep quiz because during my calculation, I round differently than rxprep and got for example, 3.4 instead of 3.5. seems stupid to get a question wrong like that on real naplex. Hopefully NABP have good programmers that can code a test program that accepts answers within a certain range.

I just did the above problem. If you don't round anything in any of the steps you get 204.54 as your final answer.

Edit: I just did it again using 81.81 and got 204.52. Don't know how you're getting 200.

180/2.2 = 81.81

81.81 X 0.25 = 20.45

20.45/0.1 = 204.5

I'm not sure how NAPLEX expects you to round. I did not round off anything prior to the final answer. Since it is adaptive and most calculation problems are fill in the blank, perhaps they have an acceptable range to allow for minor differences in rounding.

I have also wondered whether they have an acceptable range! I feel like they might, but of course they will never tell us!

On my NAPLEX, almost every one of my calculation questions resulted in a number that was very easy to tell which way they wanted you to round. (e.g. 50.04 ... 65.20 ..)

It was nice because they state very clearly whether they want the final answer rounded to a "WHOLE NUMBER" or "ONE DECIMAL PLACE".

my mistake I got 204.5 also

On the NAPLEX did you use 29.6ml for 1 ounce instead of 30ml?

I don't recall having a question where that would have been necessary.

Don't worry about rounding on the actual NAPLEX. They will be very specific about it. For example, they will ask you to round the result to the nearest whole number or 1 decimal place or 2 decimal places etc.

Keep as many digits as you can in the calculator. Round at the end to the indicated digit.
