Using the table

The table below shows the total score (trick score and bonus) for contracts bid and made.

The central column shows the level of the contract bid and the numbers in the left and right margins show the number of tricks made (= represents a contract made exactly and +1, +2 etc indicate the number of overtricks). Now the score can be found by looking under minor/major/NT and under the X for doubled and XX for redoubled contracts in either the non-vulnerable or vulnerable section. For example, If you have bid a major suit contract at the 3 level, vulnerable, not doubled, and made two overtricks, your total score would be 200 (150 in trick score and 50 part score bonus).
