    On an Acid/Base ranking question on the DAT will the weakest acid in the series always be the strongest base?

    Yes. If an acid is very weak, it won't dissociate very well into it's product. [H+] [A-]. Which means that the conjugate base [A-] (since it doesn't like being in this form due to instability) will be more likely to steal an H+ and form the weak acid. So in sum...
    Weak Acid --> Strong Conjugate Base.
    Strong Acid --> Weak Conjugate Base.
