Take your time to read instructions before taking this test.

 

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 TMA 103 exam

 

PS

 

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

 

 

 

 

Note

 

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
