Hi

JoSAA won't send you any notifications. You have to yourself check which College and Branch you have got in Seat Allocation Round 1 under JoSSA Counselling 2019 by login in the official site.

You can always check this link to know more about JoSAA Counselling 2019 in a greater detail through this link: https://engineering.careers360.com/articles/josaa-counselling .
