So I am a decent teenager and planning to apply for mext after 2 years when my 12th is completed but there's a huge problem.

See I will be only 17 at the end of my school life(2028 December) so if I am selected for mext and go there(Japan) the necessary things like Adhaar update after 18 requires physical presence I can't just come back from there also what and how can I come home in family emergencies from Japan?

Is there any way to solve this or I should leave mext

Is it ok to be actually ahead in math syllabus?

I am a pw arjuna 2027 jee batch student and I study from salim sir recorded and physical chemistry live but I have buffer in maths (sequences and series) while current batch is at basic maths. I study maths from 2026 old batch and watch 2027 live lectures recorded for revision is this ok or I need to follow current speed of our batch. This is case of only maths all other subjects are with sync with batch.

I mean everyone has their own learning speed
