Hey everyone! Thanks so much for all the help lately, you guys are honestly lifesavers..
I’m reaching out because I’ve been wrestling with an Excel issue for weeks now, and I was hoping a kind soul might be able to take a look at it for me..
So, here is the situation:
I have 10 different subjects and about 200 students.
I’ve laid out all
ten subjects in columns, with the
students listed in rows.
The tricky part is that not every student has to pass all ten subjects; some only need to pass 5, others 4, some 8, some 7, and so on... Basically, each student has a specific number of required subjects out of my total of 10.
Whenever a student passes an exam, I enter the date they took it (using this format: 1-Jan-13) into the cell under that subject's column. Exams a student hasn't taken yet but still needs to complete are marked as "undefined date." Subjects that a student isn't required to take at all are marked as "N/A."
So, this table with 10 columns and 200 rows is filled with these different markers (dates, "undefined date," and "N/A"), and every student has a different set of mandatory subjects.
What I really need is a formula that can calculate the
percentage of exams passed (relative to the total number of exams that specific student is actually required to pass—meaning I need to ignore any cells labeled "N/A")—calculated for each row per student.
Naturally, I want this percentage to update automatically every single time I input a new date..
For instance, if someone has passed three exams (three cells containing dates) and still has three more to go (three cells saying "undefined date"), that means they have 6 total exams to pass, making their pass rate 50%. Essentially, Excel needs to completely ignore those 4 cells in the row that are marked "N/A."
What is the simplest way to pull this off (ideally using just one formula)?
Does anyone know how?😕
