Good luck and try not to be too negative!
The exams are tough but not impossible – you should get them during the six sittings, most do. Remember that you can take take a few attempts at each subject, so getting 50% of them first time out isn't the end of the world! I personally struggled with one subject and despite success in the other subjects was stuck with one failure after my four attempts. I then went straight back into intensive study and brush-up courses and got them all in three months. I have 27 passes in twelve months to my name and have begun flying at last for the CPL/IR.
If you are determined, you will do the work necessary to overcome this hurdle and will not look back.
Word of advice...choose your ground school wisely.
