On the PSAT, you do not need to go through the questions in order. You can tackle the test with your own strengths in mind. Your main goal must be to attain as many marks as possible.
Even though there are no mark deductions for wrong answers on the PSAT, elimination is still a very important strategy. If you are sure that one or more options are incorrect, your chances of getting the right answer increase by paring the selection down.
There are four answer questions for each question on the PSAT. There is no mark deduction for wrong answer choices. This means that even if you have no idea about what the potential answer to a question might be, you still have a 25% chance of randomly choosing the right answer.
Make sure to take care of yourself while you are preparing for the test. Health is beyond important, and it should not be compromised. Make sure that you get adequate sleep every night and eat healthy meals.
Taking practice tests before the exam is very important. They not only acquaint you with the exam pattern but also help you understand your progress in preparation.
The best approach to practicing is to start with official PSAT questions. This will help you understand where your potential difficulties lie. Both quantity and quality matter.
Even if you are short on time, make most of the time you have in your hands. Do a lot of reading so that you are confident in solving the Reading, Writing and Language sections of the paper.
