Converting Letter Grades to Numeric

[Angelo D]

I am working on a spreadsheet in Excel for Grades for my students. I need to
set letter grades to numeric equivalents (A = 4.0, A- = 3.7, etc) then have
the final grade show up as a Letter (A, A-, B+, etc.) Part II of this is I
have 9 grades each equal to a certain % of the Final grade (totaling
100%).... Help! Thanks Angelo D

=LOOKUP(A1,{"a","b"},{4,3.70})
where cell A1 holds the letter grades and this way keep extending the values
in the curly separating them by a comma.

For Part II you can use something like this
=sumproduct((A1:I1),{0.1,0.1,0.2,0.05,0.05,0.05,.25,.1,.1})
where A1:I1 i the range where the grades are stored and the second part
arethe weights totalling one

This will get you started in the right direction:

=LOOKUP(A1,{0,"F";2,"C";2.3,"C+";2.7,"B-";3,"B";3.3,"B+";3.7,"A-";4,"A"})

Col A Col B
B- 2.7
A 4
D+ 1.3
C 2.3
C+ 2.3
F 0
B 3
C 2.229 <- =AVERAGE(B1:B7)

In b
=VLOOKUP(LEFT(A1,1),{"A",4;"B",3;"C",2;"D",1;"F",0},2,0)+IF(LEN(A1)=2,RIGHT(A1,1)&0.3,0)

in a8 across from the average in b
=VLOOKUP(B8,{0,"F";0.7,"D-";1,"D";1.3,"D+";1.7,"C-";2,"C";2.3,"C+";2.7,"B-";3,"B";3.3,"B+";3.7,"A-";4,"A"},2)

Good luck
