every application is very different, you have to roll with what's asked
My advice is as follows
1. On the FIRST page when you upload your Biometric page of your passport you MUST MUST MUST check the data is correct and change it if it isn't as the web portal takes NO responsibility for mistakes, that's 100% on you
2. When uploading documents think in terms of "what could I add here that would add value and help to support the request"
One example would be a cover letter explaining why you wish to live in Thailand and how grateful you would be to have the visa approved, not requested but would possibly be appreciated and add value to your submission. They key is to add as much supporting information to one pdf as possible and compress it to fit the requirement
