Dear members

Please provide some tips and techniques for solving costing and accounts problems quickly. My current average speed is 35-40 minutes per question (Practical questions) and I am little afraid that this may have effect in my exam. 

Daily, I am practicing costing and accounts but still at the end of the day I am able to solve 5-6 questions only :( . Calculation mistakes and overlooking of information is also a problem I am struggling with. And I think many of my fellow brothers and sisters are also facing this problem. Hence share your views to overcome this :)
