I know this has been covered here a million times I'm sure, but I don't know where.
Can anyone give me the simple answer or formula how this iis calculated. I think I know and some of mine make sense, some don't. May I buy a clue please?

    Sorry for the double post... hit the return key in the wrong field by mistake!

    The easy answer is to multiply the weight of each card you have in a set times the grade of the card, and that gives you a certain number of "points". Do that for each card you have in a particular set, then add all those numbers up, then divide by sum of the weights of each of the cards in the set.

    Hope this helps!

    Thanks,
    I think that is equal to avg (GPA x % complete) which is about right I think based on some of my sets. But I wanted to check with someone else before I complain.
    Thanks for the info,

    Fuzz,

    Check my Set Registry Spreadsheets. These will do the calculations for you. If the set you are interested in is not listed, email me at jeb@virtualizard.com and I will add it to the site.

    JEB.
