without gre and toefl can we apply to harward

No, I assume you want to apply for an engineering or sciences or arts related course. GRE and TOEFL are absolutely necessary. Some courses do not require GRE but TOEFL is very much compulsory. Hope my answer has solved your query. If it has, kindly mark it as best answer.

Hi Shabnam. You must write gre and toefl to get into Harvard University which is compulsory. All the best. Regards Manish
