The strategy that I would follow is
1. finish SC questions as fast possible; within 35 -50 seconds if possible.
2. Use the extra time gained in SC to use in RC
3. Finish CR in 2-3 minutes depending on the difficulty level.
You see the trick is, you need to read fast and still read very very very attentively. How come that is possible? well for some people it is possible, for the most it is not.
You need to define the purpose then.
SC : is all about pattern recognition. If you are fast to recognize pattern, 99% of the job is done. Purpose is : recognize pattern as soon as possible.
CR: all about reading attentively. Purpose: Do not rush, do not scramble. take your time. These are not the questions to show off how fast you can read.
RC: Now you can show off your WPM. reading with maximum speed with comprehension. this requires practice which develops with practice. and the funny thing is it is very much doable. If you could read 350 words per minute with great comprehension, RC is dudu.
