There is no specific exam pattern you will get to see for the entrance exam at Lucknow University. The exam pattern keeps changing year by year. Here is a rough pattern that LU follows. 

• GK: 20 questions.
• Reasoning: 20 questions.
• 10+2(Intermediate): 50 questions.
• Hindi and English literature (5+5): 10 questions.

This pattern is also followed for the entrance of National PG College and IT College (Lucknow) as well.

Now as you want to prepare for the entrance exam then I will suggest you visit Amazon to purchase books for the LU entrance exam. If you are an average student but your basics are clear then you can easily crack this exam.
