What is the procedure for taking admission
Go to the university undergraduate admission portal. The link for the Admission portal is updated on Home - University of Delhi during admission period. No need to go here and there the link to admission portal will be on front page. There will be a separate link for entrance based undergraduate courses.
Create an account on the portal. Fill up the form. READ instructions carefully. Pay the registration fee and relax.
I advise you to check/select all the subjects while filling in the registeration form. You will not be able to take admission into a subject(if you change your mind in mean time) which you have not selected on the registration form.
If you are not from Delhi, arrive a day or two before the cutoff is announced.
Carry atleast five copies each of your certificates and self attest them. Have a bunch of passport size photos with you.
Once the cutoff is released, be sure to visit the college within time frame specified in the admission bulletin. Carry the print-out the registration from along with the original and self attested copies of certificates.
Once college verifies your certificates, the college will update the same in the online system. You have to login again(usually after 4pm on the day you submit your documents) into the registeration system and pay the first year fee.
One EXTREMELY IMPORTANT thing to note is that you have to take admission in the cutoff in which your percentage is between the range as published by college. For example, if your percentage is 95% and a college declares its first cutoff at 94% then you are obliged to take admission in first cutoff. You can take admission in second cutoff, but only on the last day of the specified cutoff and on discretion of college. So don't take risk and take admission in the cutoff you clear.
After paying the fee for first year, take printout, atleast 10, of the fee receipt and carry them with you along with your passport size photos. This will save you from a lot of trouble especially if you taking admission in RLA, MOTILAL, ARYABHATTA where you have to run either to Satya Niketan or Vasant Gaon to take print-outs.
