The father's grand-mother had the condition: My great-grandmother is still my dad's grandma. Which in turn means his mother (the father's) had a 100% chance of being a carrier, and the father had a 50% chance. Consequently, the child has a 25% chance of being a carrier and a 1/50*1/4*1/2 = 1/400 cha...

This is generally a good question that suffered from a transposition in answer choice B (NETs/CRAs) and th...

The updated to this question should be accessible mid next week. It has been rephrased to say: "A second researcher summarizes the findings of this study, stating that downward social mobility causes an increase in psychiatric disorders.

Re: NS Verbal Practice book, section 1, Passage 6, Question 33.

Between the pianissimo which almost reaches the limit where sound ceases and silence begins, down to a range of formidable and terrifying power, every degree of intensity can be obtained from this magical instrument.

Re: NS FL#7 PS 24

I would have chosen A too, honestly. I've brought this problem up to our team, and it should be fixed within the next few days.

Re: Study Sheets

Honestly, as you feel fits you: If you generally like making things and are good at putting in the effort into putting things in your own words (rather than copying from the book or videos), then every chapter might be a great idea (seeing as you have a lot of time to prep right now).
