Should be under Route 3, recognition of overseas PE for direct entry to Tier 1 PE. My batch is the early batch, not difficult, submit forms, CV, overseas PE certs and reports. I have PEng overseas and CEng before I got my Malaysia's PEng, but they never ask me about my CEng report, only my PEng interview report. I heard new batch need to take an exam on code of conducts for Tier 1. To get Tier 2 PEPC you need to sit for the PCE like everybody else. PCE is quite tough. Don't forget to register your graduate engineer now with BEM though.

Why not do both concurrently, the reports don't vary much, you won't know if they will change the requirements or not later on.

It depends on how you define those 6 months worth of experience. Doing some field change at site is considered design work. Site visit to resolve problems can be considered as site work. For the duration of 3 years, very likely able to achieve 6 months of both.
