I did not want to go to the regular classes to clear the PCBA certification exam. So i chose to prepare online with the help of the Business Architect online mock tests. The mocks are simulated in the sense that these have similar number of questions as the actual exam to be attempted in the exact number of minutes. The format of multiple choice questions remains the same as well. So there was nothing left to scout outside. Much of my time was saved and much of my practice was in line.
