Point for each category ?

Question

Q2A have 1 point system for all the answer, but I want to calculate point per category.

Ex :  In a question about Math, an answer from a math expert will have higher priority.

Is there a simple way to do this or I have to read from the database and re-calculating everything ?

TO MAKE IT SIMPLE : my categories have 1 level, no tree structure.

No simple way but can be done via a plugin. The point calculation function can be overridden in the plugin and points calculated per new rule. This calculation happens every post update which Q2A handles automatically. But managing the new point system won't be so simple.
