Hello ,

Don't worry paper in boards are always according to blue print , it very rarely happen that paper are not designed according to blue print.

Even then don't need to worry about how the paper is designed if you have read all the topics and chapter carefully , so it is not going to be tough for you . Because questions asked in board are either easy or medium , very few questions belong to difficult cateogry . So you should focus on your preparation rather than having concerning about what if paper not designed according to blue print .
