Few if any trainer aircraft are meant to be flown from the right seat, which is undoubtedly part of the issue. You are seeing with a large amount of parallax if you can see an entire instrument and its markings at all, plus the poor ergonomics and distance involved. You will adapt eventually, but I would not feel any personal stress about it, maybe you are slower than the others but you'll get used to it.
Try setting up a desktop simulator, sit to the right side and fly that a while. Another trick is to find things on instruments to use as markers instead of trying to actually read the numbers. If at 75 knots there is a post light through your line of sight, use the post light. Another idea, take some pictures of the panel from your head location and see what you can find to help in terms of viewing angle.
