In which courses can I get admission in DU with 68% in 12th and 62% in PCM
As you have secured 62%in PCM, it is not possible even till the last counselling. Its very low % to get in DU.
Considering u as a Commerce Student, even its very tough to get in, unless you are a girl coz there are handful of girls college i.e., Bhagini Nivedita , Satyawati etc. You can have a look upon them. Thats too in the evening batch.
Coming to Humanities, You cant go for B.A as well . You can take Language or Romantic Studies oer here.
You can go for BBA , by cracking DU JAT as it is offered by 9 colleges.
Good luck!!!
