Hey Guys, If you've been preparing for JEE for a while now, here’s an initiative called “Phone a Friend” on an app called FamPay. Here there is an option for JEE aspirants like us to talk to toppers who are currently studying in IIT Madras, IIT Bombay and so onn. And the best part is, it’ll just be a one-one call with an IITian and I can choose with whom I would like to talk to. I spoke to a topper from IIT Madras yesterday and all I had to do was, download Fampay app --> complete signup & KYC → Go to Club Section → Click on PaF and book session. 👇Download the app now👇
