As I've chosen only French do I need to learn about others languages too ? Like in cluster 1 there are four languages German Russian Spanish and French

But there are four languages in cluster 1, and I want to go with French language, do I need to learn culture and gk of all four languages if yes, then where can I find the stuff to prepare

For B.A. there are three clusters:
Cluster 1: French, German, Spanish, Russian
Cluster 2: Japenese, Korean, Chinese
Cluster 3: Persian, Arabic, Pashto
Candidates may opt for three languages from two clusters only or three languages within the same cluster. The entrance test will be a common test which will be conducted along with the B.A. entrance test for 3 clusters mentioned above.
For Computer based objective test, Candidates shall be examined on the basis of their general language and aptitude test. Questions will be asked from General knowledge, General English and Elementary knowledge on the culture and civilisation of the languages concerned and aptitude for knowledge skills.
For subjective exam questions will be set in respective foreign language (french for you) and answers will be given in that foreign language only. Proficiency for written and spoken for required language is required. Knowledge of basic and applied grammar and translation from concerned language to english. Familiarise yourself with the culture and civilisation of your concerned language.
For preparing materials I told you some source before, other than that you can purchase R Gupta's JNU B.A. (hons.) foreign languages entrance exam book, which is available easily online.
Thank you
