No, you have to apply for differently for both the forms at different prices.If you are applying for the merit based admission you have to fill the form and have to select courses and colleges as well you can select any number of courses and any number of colleges. You will be charged only once for this entire process and that too a reasonable amount around 250 I guess if it not have changed from last 2 years.On the other hand if you are applying for entrance based admission you have to fill a different form that will and in that you will charged a sum per test for those which you want to take. DU conducts test for B.Tech , BMS etc. You have select these tests in a single form which is different from merit based. You will be charged around 500 for each test if the amount have nit changed from last 2 years.Best of luck for your exams hope you make it both the admision process merit as well as test based. And you may lead healthy life in DU physically as well as mentally. Be away from all shitty elements in your entire college life.
