Do dualites at the BITS Pilani Goa campus study really hard in their first year?

Absolutely true. You would only be given your BE degree from BITS Pilani when you have an impressive CGPA and showcase great preferences.

• Since the CS branch happens to be quite popular among everyone, you are required to score a great CGPA in order to pursue it. It is only possible through determination and hard work.
• Make sure you are consistent and never give up.
• Try and check out the various departments and clubs around the institute too. As they are given preference during placements too.
• Keep your academics and extracurricular activities in balance. So, one is not hampered by the other.
• Unlike the way you prepared for your JEE exams, you need not work on your studies the whole day long.
• On the other hand, you can utilize half the time of your preparation somewhere else.

Eventually, all I would say is that you simply have to work smartly and stay persistent. This way, you can learn how to balance your time with other activities.
