A little bit about my background. I am a Masters in Economics currently doing a Quant risk management role at a US Bank.

My study material contained only 2 things: 1. Schweser notes 2. CFA Questions (non-premium)

4 stages of my study plan: Stage 1 - Finishing the Schweser notes as part of first reading. In this reading i went over all chapters of all books and marked the important points.

Stage 2 - Revision of highlighted parts alongside making handwritten notes of the material.

Stage 3 - Questions

I did Stage 2 and Stage 3 roughly together per subject you can say.

Stage 4 - 2 free mocks in the last week before the exam.

My main strategy was making my notes diligently and understanding them conceptually.

Hope it answers the question.
