Hello sir....can i get admission with 79 percentage in class 12th
No school/ college take a new student in class 12 , what ever marks you have ,as half of the syllabus of 10+2 is completed in class 11 only.
But there are some schools which do so,So if you are really looking for a school after passing class 11 then go and search for them.
Yes, you might be able to get admissions in the University of Delhi for pursuing your graduation with 79% but to be true it solely depends which course you want to pursue if you want to pursue courses like ba English hons or bsc you might easily get admission in a good college but if you want to do courses like B.com, B.com hons or ba economics hons having high demand also have high cut offs and you might find it difficult to get admissions in it with 79% unless and until you have an SC/ST quota. Do remember to be precise next time regarding the University and the Course you are asking for.
Hope this might help you.
