Q. If I cannot keep up with the davening at my shul so I do it on my own, usually before the congregation. If I start the Shema with them, but if I’m late starting Shemona Esrai and can’t say kedusha with them. Is it okay to go ahead when I am davening with a minyan?  If I miscalculated, can I say tehillim while I’m waiting for them to catch up?

A. See answer above.
