ப்ளஸ் டூ படிக்கும் மாணவர்களுக்கு இந்தத் தேர்வு பயனுள்ளதாக இருக்கும். இந்த யூ ட்யூப் தளத்தில் வரும் ஆடியோவை ப்ளே செய்து மீண்டும் மீண்டும் கேளுங்கள். ஆடியோவை கேட்கும் பொழுதே கீழே உள்ள கேள்வி பதில்களை SCROLL செய்து உற்று நோக்குங்கள். பிறகு கேள்விகளில் உள்ள சரியான விடையை தேர்ந்தெடுத்து கடைசியாக SUBMIT செய்யுங்கள். நீங்கள் எடுத்த மதிப்பெண் வரும் அந்த மதிப்பெண்ணை கீழே உள்ள கமெண்ட் பாக்ஸ் இல் பதிவு செய்யுங்கள். மதிப்பெண் குறைந்தால் மீண்டும் ஒருமுறை முயற்சி செய்யுங்கள்... வாழ்த்துக்கள் மாணவர்களே...அன்புடன் - K.K.D.
