I am a female and this year i appeared for 12 which i have not cleared so i want to join a diploma course

The rules remain the same whether you are male or female... . But girls may have some concession when compared to boys. Since you have failed to clear your 12th it's not a bad idea to go for Diploma. But before taking that decision, remember 1. To concentrate and clear your diploma with good grades

There are polytechnics all over the country for which clearing 10th would be sufficient. Please get in touv=ch with your nearest polytechnic. Other options are clear +2 first then look for engineering . Also visit www.nios.ac.in to see whether you have other options.
