It helped me

The crux is to spend time on the question stem and then look at the statements

I am also struggling in CR - I know prethinking stuff and spend a lot of time on tutorials/videos

But its not working :(

Also my job has become really hectic - with layoffs- We are being pressured to put in more hours else face similar fate

I am putting more efforts over weekend - but last week my health got impacted and I had to take a 2 week break from studies

My work has become almost like 12-15 hours and keeping up studies over weekdays has become a challenge - I know I should put leaves or soemthing - but I am really scared of mass lay-offs being announced in the company left right and center

That’s very challenging to manage

A. 7
B. 8
C. 9
