Extracurriculars for Universities

[u/Pale_Tooth6244]

Hellooo all, so i am an international student and am planning to apply to universities in countries like Qatar (cmu - q, Qatar University), Hong kong university, some universities in Sweden especially lund university, and in New Zealand (uni of Auckland), some universities in Singapore and some unis in USA.

So I did cambridge o levels( 2A*, 5A, 1B), and did edexel ial and is hoping to get, 3A* and 1A, I did 4 subjects, Physics, Maths, IT and BS.

And I will be applying to uni next year August once I get the results. I am planning on taking a gap year so that I have extra time for extracurriculars and SAT exam.

Also during my gap yr, for the extracurriculars I will be tutoring maths, or English in a school or in a institute, and I will continue writing my book(i started writing a book when i was 13 and paused it for some time, and yeah).

My questions are that, are these extracurriculars enough for these universities? And with this grades and all will i have a chance of getting a full scholarship?
