so that you can be familarized or even mastered the knowledge you want.
Perfect is often used for indicating a flewless solution or result, so that no one can challenge your performence.
When we say A makesB, it has a meanig of A leads to the appearance of B, and thats' the relationship between A and B. The word 'make' also has a meaning of 'producing something'. In that case, we can also conclude that
doing X and we will gain Y.
In this situation, A is practice while B is perfect. Hence, we can say

lead to a perfect result and no one can challenge you anymore in that aspecct.
