Hii!
The syllabus for LLB at kurukshetra University, is also similar to the basic syllabus asked in law entrance exams. It contains, logical reasoning, analytical reasoning, general knowledge, current affairs, reading comprehension, legal reasoning etc.,
There are many books for the preparation which you can refer such as A.P Bhardwaj, LLB entrance exam guide by RPH editorial board, Universals legal reasoning and Gk, books for CLAT, etc.,
You will get a number of options on such books on the e- commerce websites.
Hope this helps.
Good luck!
