Test scores

I am trying to have a column that will tell me if a student has passed, they can only pass if they get a 60% score for each section, there are four sections.

eg; Cell A1 has a score out of 30 so pass mark is 18
Cell B1 has a score out of 35 so pass mark is 21
Cell C1 has a score out of 35 so pass mark is 21
Cell D1 is marked as Pass or Not Pass

so to get a overall pass the student will need to get at least the minimum score
for each test. As I have over 400 results it would be great if the final score could be calculated for me if possible in excel.
Any help will be appreciated,

There could be dozens of solution to this problem. One way would be the following:-
1) Determine the percentage achieved for each section.
2) Enter the following formula for each section:-
Parameters used:
Section 1 = a, 2, = b, etc.
% achieved = x%
First Formula: Result_a=if(a_x% =>60%,1,0), Result_b=if(b_x% =>60%,1,0), etc
Second Formula: =if((Result_a+ Result_b+Result_c+Result_d))=>4,"pass","Failed")
3) Not sure what you want to calculate with the 400 results. If you want to know how many students passed, use a countif formula
