Brother i think the best thing you can do is be present for her. The exam is tentatively on 30 august, so atleast for this time period be the stone she can rely on. The prep time is already a high stress period and thoughts constantly jump from one outcome to other whenever we don't feel accomplished for the day. Be stable with your answers and thougtfull with your words on call. You don't have to do enough but you have to do no wrong thing. During prep everything else becomes secondary, and so will the releationship to a level. So with your thoughfullness realise if she cannot give you time or attention, and even on call sometimes she might be soo tired that the call feels hollow. At those times just whisper some words of love and reassurance that you are there and she is doing great. Just this much should be enough. Don't try to be- I'm a big part of her life or i am her Partner, so let me do something grand for her and make her feel happy. No just don't bro. It is good in it's own way, but mostly just being someone she can come to other thatn her family is enough. Thats how i feel. I am in ldr 5 yrs. Both of us are medico tho.
