How can I master in each and every subject

You can, but it's not what someone should always intend as a Student. As a teacher, it's a different case as you are not bound by time (1 year for all subjects). Each item requires a particular thought pattern. Any student who is excelling in all matters is either using a lot of memorising. Hence, creativity and analytical thinking is hampered or comes from a family background where somehow he/she gets leverage over all subjects (e.g. travelling, open-minded, early subject introduction, etc.).
The second one is a rare student as any student who has gained enough wisdom will choose "Insights and Details" over "Memory", i.e. they seek to gain "insights" into the subject which leads to mastering the issue "in a long time" and not "memorise" it to learn the "in short time". Well, a motivated one can do anything that's for sure (i memorised the whole periodic table in class 8 because of a bet with my sister who was in 10).
My point is,
As a teacher, you can master all of it for employment purposes. Still, as a student I would advise not to take such a path as the present world asks for skills and how rich you are in a few subjects and how much can you apply all of it and "work with others" for the remaining as they are your limitation rather than being a hard disk for all.
BUT ALWAYS GIVE YOUR BEST
There is this one amazing thing I remember from Jack Ma, "An intelligent person will always have a problem working with others." 🤣
Hope you derive some better thoughts from this

Masters in each and every subject is not possible at one time. You need to concentrate on your proficiency subject first for masters later on you may switch to another subject becouse all subjects at one time will create mess for you because all streams are different in theory and practical as well.
