Dear Deborah Ogbonna,
Just follow some simple steps:
1.Grasp the concept, track the impact of concept on scenario.
2.Practice hard, kits, question banks. test your concepts and understanding.
3.Match with the examiner answer, as soon as your answers start matching that of examiner. you are prepared.
P.S please do not do questions verbally, always write the answers and check with standard.
These are CBE exams so you can do it as and when you feel that you are prepared. Just prepare yourself and find an approved exam center near you.
These are fairly easy exams. Read the study text and practice questions regularly.
F1 is theoratical and F2 has calculations and formulae to be learnt, So i Advice you not to attempt both Papers joint have a gap of atleast 10 to 15 Days between these two papers its depends on your preperation that which one should be first. This will increase your chances of Passing.
just get practise practise n add group revision to it.
