Stuck In San Fierro ( GTA San Andreas on Xbox One )

Hate those missions, but I had to go through all the pain here.. Driving school tests on 70% or higher like it was mentioned above..

Driving school tests need 70% to be completed, all of them.

Not all Zero missions have to be completed as the last few can be skipped of his, however I'd still recommend doing them to get the whole story.

No it's not big or even a small part of the story, it's just some side lore that I, someone who has played the story and multiplayer mod for 2K+ hours (mainly MP mod), adored.

Yes, you need. That plane mission, man, good luck.

No. To complete the drive school mission with success you will have to pass 12 tests, with a minimum of 70% of each. If you get better grades you will earn rewards and more driving skill.
