Should i join iim Trichy

Should i join iim Trichy? I am currently working in manufacturing company. My current ctc is 13.5LPA. But i dont think i can grow much here. Secondly, i dont like the city and the work is also a bit random. But i get around 90k inhand. Another option which my family is suggesting is do job for a bit 2-3 years more and then join family business. Please dont suggest to repeat cat again as i am in no mood to repeat the whole process of cat. Btw, i am from eng. Background. I have 2years of workex. Cat percentile: 96.31 Acads:8/7/7
