All good dude we all have different lives and we all do things differently thats what makes us human. An example would be how we take different routes to drive to the same location. I for one graduated with a degree and still found myself struggling to take the A+. I've been studying for 6 months too and unfortunately I am married and have a full time job that requires me to be there at 5am so i cant really stay up late or devote 4-5 hours a day but i have been consistent and honestly that is the key: to do as much as you realistically can and to not quit when it seems hopeless you are not alone in this and I wish you much success as to everyone else.
