I have a few friends from Lucknow University and according to them, for the entrance examination, it focuses more on the syllabus of your 11th and 12th commerce subjects mainly. There will be a total of 75 questions based on these subjects.
The topics covered in the examination are as follows.
Further, Current Affairs is not a particular subject but is all about what is happening all around you. It is just a basic knowledge of what is happening in the world around us and this constitutes about 25 questions of the test.
You can acquire books and study materials online for the LU entrance examination.
