Hi

Could you please provide more context? Both words have multiple meanings.

Thanks

There are already several threads about these two words, which could well be of help to you. It's very much worthwhile searching the forum to see if others have asked the same thing before you.

As sdgraham has said, this question is so broad that it is practically impossible for us to give you a helpful answer without knowing exactly what your confusion is about these two words. Can you use them in a few sentences for us, so we can see what's going on? Thanks.

By the way, welcome to the forums!

·I need to prepare for the test since now

2 and 3 make sense; 1 does not.

Either of these would be acceptable but "from" the beginning would be much more common
