Hi Venagga,

Do you mean "private independent study programs" or "homeschooling"?

Or perhaps you mean "private school"?

Or perhaps you mean "a nice private and quiet place to study"?

I see you tagged your question with the "tests" category, so this last article may indeed provide the answer you seek (also including a link below to Test prep info ctr).

If these resources aren't helpful to you, please provide more information about your need. Thanks!
