BCPM is likely important if you have a lot of nonsci courses, because the BCPM and GPA will be significantly different. The LizzyM score however is not particularly important -- I know of no school that actually uses that particular formulaic approach. It is really meant just to give you a "quick and dirty", "back of the envelope" rough idea of your level of competitiveness, which you can then compare to MSAR numbers, not as a reasonable representation of how an adcom would look at it. So I wouldn't waste much time.
