My marks in varc section is fluctuating from -4 to +8 in cat daily target test...Please guide me!!

Don't attempt more than 8-10 questions. Select 8-10 questions. Only mark options when you are 100%sure. If confused between two options try eliminating the wrong one by finding a flaw instead of selecting the right one. Read genres you are not comfortable with. 10 questions correct is 30 marks.

Daily target questions are generally tougher so its OK if your score is fluctuating.
