Estimating..... a good start for a newbie planner???

Hi, I know some basic stuff in P3 but I have little experience in actual work (S-curve, Planned vs. Target Charts of 2-storey buildings only). Many planner job openings are for high-rise buildings that require 3 to 5 years of actual P3 experience. I don’t have any experience in high-rise projects. I think I’m gonna be a Quantity Surveyor first of a high-rise project, is this a good start to become a planner of this particular project? I can’t find junior planner openings.

Thanks.
