Hey JS I asked a similar question but I think now its a hard question to ask. Nobody knows your/mine capability of learning speed etc. But I do think you could
Review the "Blind Review Method" at the beginning of the syllabus. Also, don't worry too much about the speed at first; get the logic and reasoning down first. The speed will come naturally as you practice more and more.
If you're just starting, they're not bad. Speed improvement depends on where you are up to. If you are beginning, don't focus on time; it will improve with practice.
