bhul jao sab kuch, bas bache hain do vishay  computer aur vigyan.
laga denge hum isme hum apni jaan.
aisa finish karenge boards ko,
ki finisher dhoni ka bhi ho jae apman,
abhi puri india ko jalana hai,
india topper banke jo dikhana hai,
jeetna toh apni kala hai,
kismat to apni jeb mein pala hain,
dosto dar kis baat ki hain,
paper ab tak kharab huan ho ya accha-bas ye  bolo-
वो तो सिर्फ अभी झाकी हैं ,
अच्छे पेपर तो होना बाकी हैं ।
LETS PAYBACK OUR PARENTS.
