how do I get a job in UAE with a first degree in science education and 6 yrs of teaching experience in a boys high school in Ghana? What other certificate do I need to make it easy for me to land a job.A lot of biology teachers are advertised by schools on this platform but after many applications by me I do not just get it. Is there something I must know..?
