Hi there, I am just starting out with my preparations for a consulting career. Could you please guide me on the preparation of McK PST, BCG potential test? I think I should start with brushing up with Maths skills but I don't know where to start from. I tried with GRE / GMAT preparation materials but they seem not exact fit for this preparation? On a separate note, anyone please guide me whether the first round interview (mentioned in other discussions & Q&As) means the PST & potential test?
