HELLO,

Yes, sure taking admission in class 7th is possible but it involves general process like you have to choose the school in which you are interested for admissions and check its admission policies , eligibility criteria and deadlines of filling the application form for admission.

You also need necessary documents like previous class reports and birth certificate and potentially it may require a entrance exam test or interview to confirm admission but in some schools direct admission may be possible it varies school by schools , so you should first identify the school which you prefer for admissions then you can visit their official websites for admission details or contact or visit them directly for admissions

Hope this Helps!
