XtremePapers

i prepared for it in 20 days.
Well u need to learn vocabulary in the link in have given.
You need to do these each day:
1-memorize 100 words a day (its not difficult i've done it)
2- Do Barron's Past Papers each day
3- Wish yourself good luck

one more thing leave each question u dont know as there is negative marking involved.

Ohkay, so a total of 1000 words would be enough?

Also, what score did you get?

yeah depending on the time left 1000 are okay to get you going
and i got 1850 ( didnt know negative marking was a thing at that time)
