Which is correct:
"As long as I continue to study, I will get good grades."
"So long as I continue to study, I will get good grades."
(Someone told me that to use "as long as" was incorrect in that context. I was wondering if that was true. If it is true, that it is in correct, is there a way you can use "as long as" correctly in any instances other than similies?)
They are both correct. However, I wouldn't use 'so' myself.
