Akhee it comes with time, when you finish your Quran it will be the weakest but if your constant and read EVERY day then inshAllah within a year or two you will notice your quran becoming stronger and stronger.
for me personally if you told me an ayah i will always be able to tell you atleast what surah it is in inshAllah, and most often then not I can tell you the ayah after it
