I am in class 8 and I gave ZIO this year and I am getting a score 55-60 so I’ll probably qualify.
But I want to ask that how to prepare for INOI.
I have done about 150-160 problems on codechef using python.
I know topics like binary search, merge sort, selection sort, insertion sort and a bit of dp.
I am learning c++ completely from youtube.
I am learning data structures and algorithms from places like khan academy, youtube, iarcs, commomlounge etc.
I tried to do some online courses but I can’t do a course for more than 1 day. I just don’t understand it.
I also don’t quite understand from books.
Now, so from where should I learn and prepare.
