The protest by the students' wing of the AIADMK (Amma) would be held here on September 9, he said and urged the volunteers of the party, students, parents and others to participate in large numbers.
The Centre was "imposing" the National Entrance-Cum- Eligibility Test (NEET) on the students with the "help" of the state government, thereby affecting the dreams of the students of getting admitted into medical colleges, Dhinakaran said in a statement.
"The NEET, which is taking away the rights of the poor people in the rural areas and affecting their dreams of getting admitted into a medical college, should be scrapped. Amma (late chief minister J Jayalalithaa) was determined about this," Dhinakaran said, while referring to the former AIADMK supremo's opposition to the exam.
"Since Amma's demise, we are witnessing every right of the state being compromised and this should not continue. The social justice the Tamils got after much struggle should be upheld," he added.
