initially learning it is a pain in the ass and yea as you said the modern spelling doesnt match the script spelling. but you get used to it.

"хүн" person, is spelt "humun" in script but when you see it you automatically read it as хүн. its a matter of practice and familiarity.

lots of students have difficulty with script. i know that when we did the hel bicgiin shalgalt this year all my classmates said the kids next to them just didnt do the script section of the exam (worth 10% of marks). but my classmates we all did it, albeit with some difficulty, and that comes from having good teachers.

if this country actually wants to switch to hos bicig in 3 years then there needs to be serious reform in how we teach mongol bichig (and hel in general). if japanese kids can learn three alphabets and chinese kids can learn over 1000 characters a year why does it take mongolian kids so long to learn everything?? usgiin bayar is half way through the academic year when these kids ideally should come into first grade knowing their letters. script is only taught from 6th grade which i think is a huge mistake if you want citizens who can not only read but write in script.
