Hi Sherif,
I'm not sure how much this will help, but I would suggest to review your answers, even those you got correct to make sure you understand why you got them correct. If you guessed and by chance got them correct to get to 70%, the results can be drastically different on the real exam. Also, try to get your score up to 80 or 85% (or even higher). I'm newly starting my journey and plan to take this approach myself.
