Which college should i go to if my best of four percentage in class 12 is 91%? I'm from Humanities stream , can I get admission in DU? Which college will be best suited for me?

Hello,
As you have not mentioned your category I assume you belong to general category than. With 91% in best fo four your chances of getting Delhi University north campus colleges are very less.
However you might get top colleges in South Campus. Best colleges in South campus are:

• Venketeshwara College
• ARSD College
• Motilal Nehru College
• Bhagat Singh College

However if you belong to any other category than you might also get North campus colleges i. e. KMC, Hansraj, Ramjas, Hindu, Miranda, DRC.
Ypur preference should be to get your desired course not the college, as syllabus and exam are same for all colleges.
