No, u can try harder and excel the next semester. Since your courses don’t end in semester 1 it means only half the grade is a accredited for. Also I don’t know where u reside but it’s not possible legally to fail Jr. High legally.
you may have to take summer school if not retaking the grade depending on the district. semester 1 is easier than 2, so it is likely u will fail both which results in retaking the grade
