Hi,

The admission in many of the colleges under Delhi University including Sri Venkateswara starts once the 10 +2 results are published.You should register on the common DU Portal and fill in the required details and also pay the fees.

Some colleges like St. Stephen's conducts personal interviews and the candidates have to register in their private portals in addition to the DU portal.

The cut offs of various colleges will be released and you can take admission once you clear them.

Usually the cut offs  are pretty high in Sri Venkateswara colleges. Some courses are of great demand too.

Hope this helps.
