How Do I Improve Speed and Accuracy on LR?
Fortunately, time and accuracy are essentially two ways of measuring the same thing: how good you are at LSAT.
So, to improve them both, I recommend that you work in tandem on the following skills:
1. Pattern recognition. (that link will synthesize some of the ideas you've already seen in your course videos)
2. Language cues.
3. Slowing down! It helps you avoid careless errors, which helps you earn more points (both by not missing easier questions and by not spending too much time dealing with easier questions; if you read clearly and accurately the first time, your work will be more efficient and thus also faster).
4. And always do your homework according to your study plan. It'll help you organize and manage all the above.
