@c_h: Don't worry, we all had our mentalmeltdowntimes ... You do have everything in sight already - first, for getting exam ready you have to fly more frequent. An hour every 1-2 weeks usually won't give you the training level needed to have the confidence. Try to fly at least 2-3 times a week right before having that click feeling in your head. - second, don't worry about navigation. We all get it wrong on a certain day and it is nothing to really worry (psst, just try to let this not happen on exam day).
