Reasoning for ibps so - law officer

Hi, I wanted to ask a few things regarding reasoning prep for ibps so law officer exam-

1. What are the free available videos by faculties which explain the concepts in the best manner for a beginner?
2. Is saurav sir’s banking series - zero to hero and other playlists which aired 5 years back still helpful or should I go for recent ones?
3. Where do you guys get questions to practice from? How many in a day should one do to get the pace with accuracy?
4. What is the correct order for doing reasoning- like which concepts to start and then eventually go on to- is there any or we can pick randomly.

Last, does anyone has link for saurav sir’s 2026 reasoning foundation batch, it’s difficult to get them in order of airing! Thankyouuu.
