There's heavy competition for Seats in India, especially for Meds and Management students. Students always target Govt-run institutes for higher education in entrance exams as private ones are costly so not everyone can afford them without Student-loan etc but even then it's hard to get a seat in a good private college if you didn't score well in entrance exams like JEE(for Engineering), NEET(for Meds), CAT(Management) etc, reason same competition for seats. So as seats are limited and not everyone can afford private ones they go abroad. More than half of these students are medical(MBBS) students and mainly they go to Eastern Europe, Russia, and Central Asia-USSR countries because they accept NEET scores and education is quite cheaper there compare to Indian private institutes.
