thanks.
i am currently relying on the OG, the updated ones.
Through the error log, I have found some of my weaknesses. Pretty revealing stuff.
I have always been the mathy guy and taking a lot of math and science courses in high school.. It turns out my math is the weakest. Maybe its got to do with age, I am not as sharp as I used to be. In lower years, I never had any formal training with inequalities and divisibility, in those days I tried to work out everything without having to use the quick tricks. This bit it hurting me a lot, especially in the DA section.
Particularly in the DA section, I see a lot of people using this bce/ad method, can someone kindly explain to me what the steps are?
When it comes to DA questions like "is x than 1. Any tricks or suggestions for that.
