I am very weak in studies and got only 70% marks in 12 th board so please tell me what course should i choose

70% itself a good score. for ur kind information in real time world require ur percentage marks it requires the perfection in practical scenario. whatever u do ur fundamental concepts must clear why u r doing that.more focused on practical oriented learning instead of theoretical learning

First of all remove such thoughts that you are a week student 70% is quite good marks. But you dont have mentioned about your stream if you are from commerce line then you can opt for BBA,BCA,BCOM, etc if you are from science PCM then you can do B.tech,Bsc(IT),BBA,BCA, etc so alll depends on you Ra
