greetings,

No, not at all. From a competitive exam's perspective (depending on the level of the exam) you need to remember a few important article number (not the content inside) such as:

- Articles related to Fundamental rights (all)

- Articles related to powers of supreme court and high courts

- Articles related to the establishment of core constitutional institutions (Election commission, President's office, emergency, etc.)

- Articles related to reservation, SC/ST and OBC categories, etc.

other than that you also need to keep in mind the various schedules of the constitution (just a basic knowledge of what each schedule holds inside) and the parts of the constitution.

All this knowledge is not to be learned by heart but be kept in mind. You need to be able to recognize a famous article such a Article 21 (right to life) or Article 32 (writs in SC) and don't need to remember the content inside.

Good luck

I am assuming that you are talking about  DULLB exam.
