The ventral portion of the medulla oblongata contains the medullary pyramids. These two ridge-like structures travel along the length of the medulla oblongata and are bordered medially by the anterior median fissure. They each have an anterolateral sulcus along their lateral borders, where the hypoglossal nerve emerges from.
Assuming that you mean the FICO score, the highest is 850. In order to have that score, one must obviously have a perfect payment record over a long term and low (or zero) credit card balances, but the other essential ingredient is the length of time accounts have been established. A revolving (credit card) account ten years old or older is a definite enhancement.
As far as FICO scores go, 692 is on the high end of average, as the scale ranges from 300 to 850. Anything between 700 and 749 is generally considered a good score, with the best scores ranging 750 and higher.
