Your arrows are probably hitting way right because you haven't got your eye over the arrow. If the arrow seems to be flying to the target from the left to the right, that means your eye is to the right of the arrow, and you will miss to the right.
Try canting your bow and canting your head to match the bow cant. At some point, your eye will be over the arrow and your arrows will seem to be flying directly at the target. Or, with the bow upright, just tilt your head until your eye is over the arrow, although if you do it this way you will have to get used to looking through the string.
