ok, now if the final exam will count as (2) test grades
85+68+92+155=400 divided by 5 test =average of 80
85+68+92+75=320 divided by( 4 )test average 80
but now if you have to count the final exam as 2 grades there will be 5 test you would have to divide by your total,in that way your test grade will have to be at least 155 to have an average of 80
