why I did not do corrections

In this blog, should not say sorry right?? Opps!I said it! I did not do it properly as I could not remember how to do it( not that I purposely don't want to do) Some I forgotten though...... my bad(mostly)not your fault though. Blame it on me being careless. Some questions I did not do working and i was too hasty to hand it up. Anyway, thanks for explaining it. Well now I'd understand....hope so at least....don't want to fail my area on triangle test......Kind of apolegetic for wating 15 min of ur life scolding me. Next time, I'd try to avoid doin corrections like thrash.(how many times I tried but no sucess....)
