Addressing a public meeting of the party here, state unit chief Tamilisai Soundararajan also said BJP would organise demonstrations on September 14 in support of the National Entrance cum Eligibility Test (NEET).
She said it was Prime Minister Narendra Modi who helped poor students pursue medical education and that was the main reason for NEET.
Referring to the meeting organised by the opposition parties led by DMK here against NEET yesterday, she said it was negative politics and would not help in the development of the students' standards.
Attacking the DMK, Soundararajan said though the party was in power for 18 years it could not retrieve Katchatheeu, an islet ceded by India to Sri Lanka in the 1970s', but now it was talking about it.
She assured that Tamil would be made official language if BJP was elected to power in the state.
The BJP leader charged DMK Working President M K Stalin with speaking about love for Tamil for self-gain.
