Hello.
B pharma, Bvoc in MLT and BSc MLT has entirely different scopes , b pharma is fully drug and medicine oriented while Bvoc in MLT deal with the technical laboratory work and BSc in MLT provides you opportunities for further study and research.
But if we see   with the scope and salary perspective
So b pharma course has higher scope, and after that you will have good scope in b.voc in MLT and salary is basically depends upon your work.
Best of luck.
