Hello.
In my point of you : olive baord.in is generally tougher than the usual levels. So, it basically increases your level and makes you accustomed to tough paper too. It, s always sad hope for the best and be ready for the worst. This what oliveboard does. The mockes are of a good difficulty level. They have some tough and some easy mocks so that you get accustomed. The Question are never repeated and analysis they give of your prepartion is not what you get in other mocks. As compared to actual exam, mock test created by oliveboard are slightly tougher. If you are scoring 80% markes of previous year cutoff consistently, you can easily clear the exam. Also content wise they have good variation. Giving tougher mockes than actual exam has an additional advantage then you wont be surprised if IBPS increases diffculty level of the exam. Also, in actual exam you are able to solve all the Qustions easily.
