Are Vebal sectionals in cracku tougher than cat LOD?

yes , too much.

No. If you're talking about the sectional tests, then they are at par with CAT level of difficulty. But if you're talking the the verbal section in mocks, then they are slightly difficult than CAT.

Yes, they are but only focus on score rather than focusing on percentile, if you are able to score 25+, then on D-day if everything works according to you, you may end up scoring 90+ percentile
