4 years later got off of the waitlist so help a brother out please 🙏

I finally got off of the waitlist after like 4 years. Been doing gigs dd, grubhub instacart uber eats. I only work on summertime due to school. I know people been doing much easier with amazon flex but not sure how accurate is it. My questions are:

I just submitted my application and it’s under review. It will come out clean eventually and i will be able to deliver but is there time limit ? I mean i’m not even going to be back to the states until july so once i signed up am i good or do have to like make my first batch within a certain amount of time ? Or just like grubhub if i dont deliver more than 3 months do i get paused and need to send an email to get reactivated ? Thats the main issue.

Other than that, do you think doing flex full time is better or should i do flex at the beginning, early morning till noon, afterwards with food delivery?

I once saw a post people were trying clocking out at the last minute so they can get some sort of pay ? What was that about or is there something that amazon pays as a guaranteed payment?

Lastly, if the batch i took says 4 hours total 100$ pay and i finish it in 3 hours. Do i get warning for being so quick or smg meaning reckless driving. Ik amazon does care about this bs more than any other company. Or, does delivery order matters? Out of 10 deliveries, first 5 next to each other, 6 th is across the town and 7 is where the first 5 is and 8 9 10 is where the 6 is. Do i have to follow one by one or can i skip to 7 from 5 and then go to 6 ?

Thank you all in advance 🙏
