Please help.

Answer 1

You can declare another variable to count the students who have higher marks than 70 and print it outside loop.

Answer 2

count is a random name of a variable rather than a keyword. For that, you can use any name you want.
This is the common way to solve a challenge something like that

var Tahiti = 0
for()
if()
Tahiti++
console.log(Tahiti)

2nd code is little bit right but you are increasing scores not counting number of students.

var count = 0;

for (let p of scores) {
if (p>=70){
count++;
}
}

console.log (count);

Answer 4

Ok. Thank you Simba . I will try that.

Answer 5

A͢J Thank you for pointing that out. It makes sense to me now. I’m not making excuses, but the tutorials preceding these Code Coaches do not make it clear how to solve these. Thanks again.

Yes there is less information but not very less.

Check this statement "count number of students who pass with 70 points"

So simple you have to count if score >= 70

Answer 7

Thank you Simba for that very helpful explanation!

Answer 8

A͢J Yes but I was referring to the use of the count keyword and variable, which was not covered in the lesson prior to the Code Coach. I’m not sure it was even covered in earlier lessons.
