MUST READ: Signs and symbols for 2017/2018 NECO GCE runs on ceewap

As earlier mentioned on this blog, and as we have promised all our
prospective candidates for 2017 WAEC runs,we have finally compiled
all the signs and symbols that will help you in Mathematics,Physics
and Chemistry and we have also
interpreted them the way it will be easy for you to understand while
writing WAEC , so that you wont go to the hall and start
messing up,thereby wasting the efforts we have made towards giving
you the best to make sure that you smash A's in 2017 WAEC.
So, listed and explained below are the signs and symbols as they
will appear in our 2017 waec runs.Please, start now to study and
memorize them.It will help you alot.

Tables, Radiativity Diagrams
Table1
A table of this would be computer as
follows
X:1,2,3,4
FX:4,6,8,10
F(X-Xbar):10,8,6,4
Table2
A table like this would be computed as
follows
Particulars: maintenance,salaries &wages,
Purchase of
Drugs, total
Amount: 2500,1000,2000,5500
Logarithm Table
Tabulate
No:92.63, Log:1.9667
No: 2.914, Log: 0.4645
2.4312
Antilog = 269.9
Therefore 92.63*2.914=2.4312
