I will be entering uni in less than a year, I will be pursuing a degree in computer science.

I want to some day be able to understand "string theory" ,"quantum gravity" (as of now these are merely buzzwords to me) and understand the standard model in and out (so QFT, QED, QCD) even GR! So far my knowledge is up-to the level of introductory physics books like Resnick Halliday Krane or University Physics by Young and Freedman. I also recently started reading the second vol of the Feynman lectures and I think I will be done with the entire series by the end of the year.

Since I will be studying comp-sci I highly doubt that I will learn the necessary math required for the topics mentioned above, so during college I will have to teach myself the math and then the physics.

So will it be possible for me to learn all those topics simply from textbooks? I won't be taking exams to see where I stand understanding wise, and ofc won't have someone teaching the subject to me.

Say I continue self learning physics approximately how many years could it take me to understand these ideas(I realize this is a bit vague as it depends on way to many factors but I guess I am just wondering if it takes a physics major about 6-7years+? how long would it take me? or is it simply impossible?)
