Sorry, I didn't' realize that you were working at the commercial level, but I think the answer still holds. To be honest, though I used DUATS (which was then pretty new) for my instrument and a spreadsheet I wrote (which incorporated my CFI's 1 minute/1000' rule) for the commercial.
For the written, I don't recall the questions having stuff that would require that kind of climb calculation precision.
