Chemistry Post UTME Practice Test For All Institutions

Prepare Yourself for Your Post UTME With this Free Post UTME Practice Test For Chemistry

You have effectively written your JAMB – UTME (United Tertiary Matriculation Examinations) and your outcome was discharged as well as qualifies you to write your Post UTME screening examinations for your school of choice. Congratulations on your accomplishment in your JAMB.

Not everybody that sits for the JAMB examinations turns out fruitful. Some don’t have their results discharged for one reason or the other. Some have their outcomes seized. The fact is that you should be grateful that is not the case for you.

The next hurdle to cross and scale through is your school’s Post UTME examination. Some people like to call this exam Post-JAMB. Some universities and polytechnics prefer to call the Post UTME exam, ‘Universities Matriculation Screening Test’.

This may be a one or two-day exam (as the case may be for the institution) set and conducted by your school or institution off choice (university, polytechnic or college of education), for admission of candidates.

Various universities, polytechnics and colleges of education set or conduct their Post UTME or Post-JAMB questions differently and of course your own Post UTME exam paper will depend on your JAMB subject combination. In this case, this Post UTME practice test is for post UTME candidates for all institutions with Chemistry in their JAMB – UTME subject combination

This FREE Post UTME Practice test cover sample past Post UTME questions on Chemistry that have been repeated from various institutions.

If you are able to score a pass mark of 60% in this sample chemistry practice post utme test of 20 questions in the stipulated count-down time of 20 minutes and familiarize yourself with the pattern of questions, you are sure to perform excellently in this year’s Post UTME exam for Chemistry

If you find this test helpful, please do not hesitate to SHARE IT with others, that way you are being your
 brother’s keeper.
