Exam strategy

Can you please let me know how should I approach timings in RC questions of
the second section in verbal? If I have 23 mins and I spend 7-8 mins on TC
and SE. How many RCs do we typically get and timing for each?

This is the structure of the second verbal section:

For timing, I would say maybe around a minute per paragraph to read slowly and carefully and around 90 seconds per question. That’s just my thoughts though.
