Hello!

I have a couple of questions and need help figuring out if anyone has advice please share.

First- i'm struggling really badly with Necessary vs Sufficient - I believe my sufficient I'm starting to get better at it but still iffy. But necessary I can't seem to get, I've even put it in a real life situation and still nothing.

Second - I use my tutor notes and drill on 7sage . But they have different wording for RC passages. For example like my tutor has normative passages, descriptive passages, and comparative. But 7sage has something completely different and while drilling I can’t figure out which is which. If you can explain or know which passages is which. Please let me know!!

Third - my tutor question type is built the principle which he has in brackets (justify the argument) I'm trying to drill this but I'm not sure what question type built the principle is, I've done principle under drill and it doesn't seem like that's it and seems like a different one, does anyone know.

And lastly oof - tips on Inference questions, I've tried everything adding therefore, building a puzzle nothing.... just not sure they all seem right!! ahh

If you have any tips please let me know!!!
