The answer is yes but with lots and lots of conditions.They are:
1)Your concepts are clear and you have been studying seriously in past.
2)You have covered the content given in the syllabus and you just need to give it a finishing touch.Just to be clear, finishing touch means revision.
3)You have confidence in yourself and you are fearless.Fearless doesn’t relate to making wild guesses in exam and ending up cracking yourself.
4)You are lucky on the day of exam and the question paper contains a lot of things from what you studied recently and small things from the portions you left uncovered.(In case you’re not satisfying the 2nd point)
5)You’re smart enough in cross checking the options.
Otherwise i must say ‘NO’.
Thank you for reading.
