Never bro . Never.
Yeeah okay in ninth grade i was having trouble with simultaneous equations and i watched this video and it helped me a bit but when i concentrated yeah i found out if you put values in your calculator to solve the equations it gives you two answers and you just basically reverse the procedure if you know what i mean(H).
Plain sailing after that.
Videos didnt help.
And for the tutors. Unless you live in Greenland there is no way you cannot find a tutor. Pakis and Indians are every where. EVERYWHERE
