Question about Montgomery county voting

Hi everyone! I’m new to Texas as of the past few months, and I was voting in Colorado for my entire 18+ life before that. Colorado has mail-in ballots as default, so we always received ballots weeks ahead of time, spent our time going through them and researching everything on it, and I knew what was going on. There was an abundance of voter guides and issue/candidate explanation online. I’ve also never voted in person at a polling location.

I am preparing to take my husband and I in to do early voting at some point this week or next, and I have a few questions.

First: I looked up the Montgomery county sample ballot and I see that there are no propositions on it, just candidates. Is this correct, am I looking at the right ballot? I don’t want to have to parse through sometimes confusing legal jargon for the first time at the polling location and choose wrong.

Second: is there anything I should know about voting in person? We have our IDs of course, we are registered, we won’t wear political gear. Am I allowed to have my phone on me? Can I bring my notes on who I’m voting for with me so I don’t forget (I’m voting a pretty straight ballot but on the back there are unaffiliated candidates and I want to make sure I’m voting for the ones I’ve chosen after research), or should I come with those memorized?

Any other advice or nuances you have to tell me? I don’t know why I’m so nervous to vote in person! I’m a little intimidated by Texas’s…reputation…when it comes to voting.

Thank you very much!
