Hello Shreya

BA is generally a 3 year course and not a 1 year course, so the years will be 2019-2022.

About the admissions, the colleges which take merit based admissions generally release the form in the month of May and if the admission is Entrance based then you will have to check on the particular college's website.

For more information about any particular College's admission, you can ask us again

Hope it helps;
