To be honest, I don’t think there are better resources to practice non-match based DS outside the OG Guide and DI Review Guide questions. In fact, there are some debatable OG questions in this segment, as many experts have differed from the official answers because of conditional uncertainty. My advice would be to go through all of these questions carefully and notice the common patterns.
Beyond that, as others have rightly pointed out, getting better at verbal reasoning, especially assumption-family questions, will help you spot loopholes in the given statements. So focus on developing strong reasoning skills and try to anticipate the assumptions. You might end up arriving at the right choice more consistently.
