I'm sorry, I shouldn't call you garbage, but I'm also a senior three student and I'm speechless about the future. If you want to practice this topic, I suggest you buy a Longmen 5+3. This book is good. I suggest not to practice on the computer, which will affect your thinking. If your concentration is good, then I am oversensitive. Besides, sitting in front of the computer, I really can't think of your first question.

I can't type math slogans, only how to pronounce them: C 88 times C 2 1 times C 44 times C 44, and I forgot whether it was c or a, so I forgot all about sitting in front of the computer.
