With this score I would highly recommend to study a little bit more and rather retake the test. If you would get the british council book (even from library for free) and follow the guidelines as well as use youtube to back it up, there is definitely high chance to score at least 8 in L and R. It only takes practice.LRWS (5.5,5,6,5.5)
should i apply EOp
For speaking, I would recommend listening to BBC radio and as well as many english youtube videos as you can. For writing, best for me was reading english texts and books and gradually improve in this as well.
