A few of my friends are CGC Landran alumni and their rutin at the institute was somewhat like the following.
Next morning, you have the same routine which continues till Friday. College is off on Saturdays and Sundays. This routine that I have mentioned goes on for the next 3 years. Till then, you'd be categorized as seniors and prone to mass-bunks. Plus when you're in your 4th year of college, your timings would just be from 09:30 to 02:00 PM.
Once a year the institute celebrates Parivartan fest, sports day, Baishaki festival, etc. Each branch also has its separate fests in which students from different branches can take part. All in all life at CGC Landran will be quite fun.
