A little background: I am currently a sophomore (studying mathematics) at an unknown university in the Middle East. My mother is European so it does not make sense to study mathematics in the Middle East when I have the opportunity to study in Europe but the problem is that my father does not let me to live in Europe and if I will, he promised that he will cut me off without a penny (my mother does not have a job). Nevertheless I am determined to go and live with my grandparents next year but this is where the problems actually start: I missed the deadline for next year's applications and the school I want to apply does not recognize my previous studies so I have to start from the beginning. Further, my grandparents live in a small village in that European country so I won't be able to attend lectures in a school or discuss mathematics with other people (on a blackboard).
Questions: Now that I will be completely isolated next year, what should I do? I am interested in topology, currently taking a differential topology course (covers the first 30 pages of Milnor's Differential Point of View, have taken an algebraic topology course (homology and an introduction to fiber bundles). I am also interested in physics, mainly general relativity. Naber's Topology, Geometry and Gauge Fields seems to be a good choice for self-study. Or should I strengthen my background in more foundational stuff like linear algebra, algebra, analysis for the year after? Or maybe I should do both? Also, how will I get motivated? Even now, although I am taking a course I like, I get easily distracted and don't feel like studying. If possible, how can I turn this lonely year to my advantage?
Apologies for my English and overusing the word "European". Thank you for your patience.
