What is the condition of general berth in train from vns to kanpur?

So I am a student from Varanasi and need to go to kanpur for two days, next week for an exam. I don't know if I will get confirm seat as there's 45+ waiting (and I honestly don't wanna buy VB). So I wanted to ask if it's possible to travel in general berth? (I am not from UP...so it will be my first time travelling in general berth of UP...so I wanted to ask so)
