I would like to add that you should start using your analog watch to keep track of time instead of the little e-clock on the app. The app should be used only for the directions, 5 minute warning, and distractions.
Depends on your proctor. I got shafted once and given a warning for bubbling in a completed answer after the proctor announced to put our pencils down.
thanks all for letting me know about the distraction part. I believe I would still greatly benefit from practicing with the announcements at the beginning/end of the sections and especially the 5 minute warning.
I usually bubble before I turn the page for LR, every game or passage for LG and RC. At the 5 minute warning I bubble everything I have so far on that page, and then I bubble question by question until time is called.
