I am not able to perform well in varc section. In verbal I am doing every para jumble and every para summary wrong. I am not able to come up with a strategy to solve this section,what should I do to improve

Actually my Varc score is not good and even having difficulty in maintaing accuracy more than 60 both in Cracku Mocks and sectional and CDC flexi And CdC pro mocks
so what should I do in rest of remaining days to balance VARC section
should I focus more on weakness or attempting more mocks ?

VARC - Will these tough Cracku Sectional Mocks help us?
