There are 40 questions which you are to answer in 15 minutes that gives you roughly 30 seconds per question.


If you can get at least 60%, you can be rest assured that you’ll ace PHY 103 exam




In a normal exam you will be asked between 40 – 60 questions but I only arranged 40 questions




Do not be in a hurry to answer the questions

Do not waste time on a question you don’t know

Move as fast as possible and starting with questions that don’t have calculation first to save time

Always crosscheck

Don’t be in a hurry to submit, you are not in a competition

Don’t be scared. Getting an A is easy

Don’t be over confident, you can end up a D, E or F. Calm your blood, no be only you sabi book
