Limits and fits
(OP)
Hi, what is the correct way to dimension upper and lower limits for holes on a drawing. Should the MMC be above LMC? OR the higher value be above the lower.I prefer the latter to avoid confusion but I have been told that the former is the correct way.Please advise

The point is, no one can tell you what is right or wrong until you tell use what standard you are using.
RE: Limits and fits
The high limit (maximum value) is placed above the low limit (minimum value). When expressed in a single line, the low limit precedes the high limit and a dash separates the two values.
You may also find it on Y14.5-2009 Sec. 2.2 at page 24 as well.
