taught-taught ..... and reinstalled the OS on his own head
was already in the 8th lesson. and now everything from the beginning.
maybe you can connect with a cable, climb into the vault and change something there?

Answer 1

If you really learned, then going through again will not be a problem. And repetition doesn't hurt. And it will be much faster than figuring out how the application stores data and changing it.

Answer 2

you can
reverse engineer the application, see how it works from the inside and break the mechanism for blocking unfinished levels
while you carry out these operations, English will learn on its own along the way - a double benefit
