Thank you for submitting homework task-2 in crypto-academy.

I plan to keep my keys save in a pdf file first that is downloaded during the time of download and then i create a separate pdf file which i keep in my pc, my mail and on my google drive.

Don't take screenshots, don't store your PDF file or key in email or google drive. The best practice is to write it down and keep a hard copy. Better divide it into 3/4 parts and keep them in different places.

To Restore a wallet, First you need to create wallet.
When we created or joined the Steem Trx Integration, we downloaded a PDF File where we had our tron keys, So when using Tron link pro, we just have to Place our private key in the App and then we could easily access our wallet using the Private key. This can also be done using Mnemonic key or KeyStore File.

I was expecting more details with screenshots and step-by-step methods to create/restore a wallet, that way, you get to know both the things-- How you create a wallet and how you restore it. So in any unforeseen event, you will always remain assured of your fund as through such tasks you get to know more details about wallet security and restoring a wallet, and unlock the fund. So you should gain sufficient user-experience as there is an extrinsic motivation(upvote) attached to it.

Thank you.
