do they give rough paper for BITSAT exam??

Try to make out what are the weaker points in the field of PCM, work harder on them, download concerned topic papers and practice them, define a proper time for practice, join some reputed educational institution for getting training and finally appear in the tests Jeemains and Jeeadvanced,....join counselling rounds by Josaa and get to know about your allottment, else try at other reputed institutions, like – Shivaji Uni, Kolhapur,......................Lovely Professional Uni, Phagwara,............................BITS Pilani,..........................Inderprastha Uni, Delhi.............     and pursue your graduation from there followed by placement in top rated MNCs,....Good Luck
