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 CHM 101 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

Please I don’t know if it is the website or my phone. It’s hard to change my answers. When I tried doing so, it might end up picking another answer or just not pick any. Meanwhile an indicator shows that one answer has been picked. In the end the website shows that I didn’t answer the question in the end.
