u/The-Best-of-Best

Every now and then I come across people posting good used phones at a reasonable price on OLX but i have heard from family and friends that OLX is mostly a scam so I am writing to ask if taking a risk with OLX is worth it?

I have been wanting to learn Persian for quite some time but I never had the time but this summer break, I finally have it and I was wondering how long would it take for me to go from not understanding the language to actually being fluent in day to day conversation?
