Hi Khushbu,

DU JAT is not a simple entrance to be able to crack easily. You surely need to have an idea about solving questions in a faster pace and also have access to good study material. For such reasons, coaching becomes useful. It is surely worth, but do not rely only on the coaching. It is your hardwork that determines your success.

Some students are more comfortable with self study. Then you can study with the help of online resources and by solving many mock tests. 

All the best!
