Glider Pilot Question

[jai6638]

I contacted a glider club in New Jersey and they told me that on average, I would need 35 instructional flights and 35 solo flights?

Is this an accurate estimate or is this on the higher side?

Thanks much.

P.S: I have logged 70 hours in a Piper Warrior if that makes any difference but do not have a PPL ( because I'm 16 )
