#5140 The Right Pray on the Right Place

Hello Rav, Sometimes I need to daven at a minyan where I need to leave the minyan early in order to be on time for work in the morning. I’m able to stay until the kedushah during the repetition of the Amidah. At that point, I could either leave the shul and finish davening in another room OR I could finish davening in the shul while the normal services continue (repetition, tachanun, etc) .

I’ve always tried to be very careful not to do or say anything during the "repetition", so to be in there and davening tachanun, etc during the repetition seems strange to me. I’ve seen people do this, but I wasn’t sure if this is the correct approach. Either way, I will need to leave the shul before they are done shacharis. Which is preferred?

Thank you!
