I do not think
@Bilal9 proposed Bengali as the medium of instruction. He proposed basic Bengali as a subject for foreign students to be included in the curriculum. Indians are foreigners in Bangladesh the same as Nepali, Bhutani or Afghani students.
@Bilal9 is right about this. Every foreign student must learn Bengali so that they can communicate with locals. This is important because they usually stay here for about six years.
Why are you comparing Indian languages with Bengali in BD? It is an independent country with its own national language. Foreign students must be taught this. India's underdeveloped languages are no concern here because Bengali is very developed.
He mentioned
And classes should at least partly be taught in Bangladeshi Bengali.
People from Manipur or Punjab study mbbs in Karnataka for 6 years but whether they are from north or east none of them go on to speak or learn any local language, same case for foreigners studying therein.
Even in China,they don't really make it mandatory but provides an optional choice ,but most students comply on their own accord for free language classes,most girls partake in it to simply be able to better understand tv drama or webtoons.
Bangla language of Bangladesh is still Bangla might be altered version of W.Bengal version,more similar to that of Tripura,therein Tripura,Bangla medium are seen as backward by locals actually and not just by indigenous people but also the Bangladesh immigrants.Schools and colleges are rated from their fluency of the teaching staff in English.North-South iNDIAN don't have any affinity toward each other's language as they all vye for their own linguistic supremacy while denigrating one another and for East Indian( North East) they will honestly avoid any college with less than 100% English curriculum, like a plague.That's why I mentioned what I said.
"Some South Asian Countries"...well there are only 6 Countries here...nobody said Russians and Chinese come here to study...but you are correct poor Nepalis,Bhutanese,Pakistanis and Indians(like you) come here to study...nobody seems to find it gross or "incomprehensible" unless ofcourse they suffer from an identity crisis whether they neither have their own culture nor a country.
Every year many students from India, Afghanistan, Bhutan, Pakistan, Maldives, Nepal, Sri Lanka, China, Russia and some African nations get admitted to both public and private medical colleges in Bangladesh, which offer high yet affordable standards of education.
Russia is one of the alternatives for China,but even Russians flock to China,I've seen plenty in medical colleges,for China offers much higher quality education by now.
And you don't speak on behalf of anyone,I'm not superimposing my opinion,don't get your panties twisted,that's simply how non-South asians feels about any South Asian language,or anything south asia,zero softpower appeal and no practical use,simply too uncool/unattractive and weird for young students.Nobody's going to BD to sit through classes in Bangla language while struggling to construe anything.
