how to solve mathematics mcq with short prieod of time

1.Elimination Method
In this method, I would eliminate those options which are not relevant or odd with the question asked or among the choices given in the choices of answers.
2.Close Answers
Then sort the rest options according the more possible to the least possible one.
3.Tick the Answer
In this part after sorting from more to least expected one, make sure if you could apply any logic of subject or any other analyzing you can do so. Tick the one which is more relevant and highly expected one.
