Alcanzar vs. conseguir?

[EmpanadaRica]

Another question..

Is there a difference in the use of 'alcanzar' and 'conseguir'?

Alcanzar I think is often used as to obtain, or to physically reach? Can it also be used as ' to succeed at' or 'to achieve'? (I think I have come across it being used in such a context?)

And in which cases would it be better to use 'conseguir' in terms of succeeding at something, of achieving something? Or are they more or less interchangeable?

iMuchas Gracias!
