Yes. If you click on "End Block" before your time runs out, the remaining time will get added to your break time. I am sure you know, but I just want to say that do not rush through the exam just to add more break time, or just to leave the center early. Good luck!
Thank you! I would never rush, but thanks for the advice anyway. Even an extra 1-10 minutes added to break time is good between each block! Good luck to you too!
