Candidates can take admissions against vacant seats in some select institutions
Most of the institutions finalise the admissions to various courses by July/August of the year. There are some institutions where inspite of all the counselling rounds, some seats remain vacant.The candidates who were not successful in getting admissions even after meeting the eligibility criterion, should keep in mind that there are still some institutions which are offering admissions to select courses and announcing it in newspapers as well as internet sites.
So, such candidates can visit the websites of such institutions and find out about the residual admissions still going on.
As per my observations these things happen to start during August/September months of the year and students should find out these opportunities by visiting the website of the respective institutions.
