No, you would not be able to surpass the cutoff (which is minimum of 300 out of 450) if you only prepare for the 12th syllabus. The 11th syllabus is as important as the 12th and carries equal weightage (might vary a little bit). It is advised that you prepare both the 11th as well as 12th syllabus.
