Too bad you do not understand the aligning process.
Cem and many other people have mentioned this many times and it is a pretty good knowledge to have.
The Boardofstudies wants to show that they are producing smart kids, so students who get a fail mark <50% will get pushed up to around the band 1 cut off which is 50. This is around 50% of the students who sit the exam. Since they get pushed up to an Aligned mark of 50+, students who scored a better mark will also get pushed up and so on.
Anyway, so in reality, (these marks are for instances) they can be
7/50 - 50 (Band 2)
16/50 - 60 (Band 3)
24/50 - 70 (Band 4)
31/50 - 80 (Band 5)
39/50 - 90 (Band 6)
