Listen brah... Nehru was a very avg/below avg student. The only reason he went to those places is because his rich dad could pay to send him to England.
On his own, Nehru wouldn't have been able to sell tea.
Luckily for Nehru. his father Motilal was President of Indian National Congress. So in 1929 Nehru inherited Congress Presidency just like Rahul inherited in 2017.
Top diplomatic postings. No college degree even.
