Alternative Methods to doing Medicine?

So i know this question gets asked daily and i am sorry for pestering but i really have not a clue what to do in University.Originally i wanted to do medicine (and still do) but i am taking two National 5 this year so now i cant. The thing is i am moving to the middle east after whatever course i take because i must support my parents which obviously means i need a decent salary. It must also be a job i can easily get cause i dont want to waste 5 years of my life and end up not finding a job anywhere. Grade wise i am predicted to get mostly A and B in Chemistry, Geography, English, Biology. I see myself getting either a B or C in maths in physics. It should be noted that Maths and chemistry are National 5 level but i am doing them next year at higher level and biology will be advanced higher. Any Suggestions? is there a way to get into Medicine/ Dentistry and if not what is a good alternative?Thanks.
