How to decrease, taking only one number from the other value?

In the final value was to have the total of the notes greater than 7, another condition would be that the user has to enter a number between 0 and 10, then any number outside this would give "invalid message", and would have its decrement, so for example if the user types: 11, 9 and 8; instead of appearing in total 3 notes > 7, it would only appear 2 ... But I can not do it, so if anyone knows how to solve it, or another way to do it, talk there coments ... Thank you in advance. >

#include <stdio.h> 

int main () { 
    int aluno, i, alunosComNotaMaiorQueSete = 0;
    float nota;

    printf("Quantos alunos fizeram a prova? ");
    scanf("%d", &aluno);

    for(i = 0; i < aluno; i++) { 
   
        printf("Digite a nota do aluno %d:\n", i);
        scanf("%f", &nota);

    if (nota<0 || nota>10)
   { 
        printf("\n Nota Invalida\n");
        alunosComNotaMaiorQueSete--;
   }else if(nota>7 && nota<=10) 
   {
        alunosComNotaMaiorQueSete++;
   }
    }     
    printf("Alunos com nota > 7: %d\n", alunosComNotaMaiorQueSete);

    return 0;
}

You do not need to decrease only sum if the note is larger. Nor do you need to say that the < 10 in the else if so it will only pass to the else if if the condition of the first if is true.

#include <stdio.h> 

int main () { 
int aluno, i, alunosComNotaMaiorQueSete = 0;
float nota;

printf("Quantos alunos fizeram a prova? ");
scanf("%d", &aluno);

for(i = 0; i < aluno; i++) { 

    printf("Digite a nota do aluno %d:\n", i);
    scanf("%f", &nota);

    if (nota<0 || nota>10)
    { 
        printf("\n Nota Invalida\n");
        //codigo antigo que nao é preciso: 
        //alunosComNotaMaiorQueSete--;
    }
    else if(nota>7 /*&& nota<=10*/) 
    {
        alunosComNotaMaiorQueSete++;
    }
}        
    printf("Alunos com nota > 7: %d\n", alunosComNotaMaiorQueSete);
    return 0;
}
