Try to always sight-read hands together. Having said that, if you’re a beginner and you’re still learning the treble and bass notes, consider starting hands separately and then hands together once you’re familiar with the notes in both clefs.

Just starting sight reading and of course hit some wrong notes. But since I’m playing through the music without stopping, I don’t always know when I’m playing a wrong note. Is that a problem?
That’s a good question. I think it depends on why you are practising sight-reading. If you’re not preparing for a sight-reading exam, I think it’s fine to slow down or to stop when you hear a wrong note and correct it. People (me included) give the advice of never stopping but I think this only applies when you shouldn’t stop – either during your sight-reading test or when you’re accompanying someone and you need to play in time with the other player. In the early stages, I think it’s important to develop the skill of detecting mistakes when you’re playing from the score, by ear if you can rather than by checking the piano keys. Ideally, you should sight-read at a tempo where you can play as accurately as possible while also keeping in time. If you find yourself hitting wrong notes all the time, then it’s probably an indication that the music is too difficult for you to sight-read or that you are taking it too fast. I hope that helps.
