Most of the questions have been collected from Past Papers
So far May-June 18 and October 18 have been covered.
Book suggestions:
The coursebook is not much helpful, so go for these book instead:
1. Cambridge International AS and A Level Physics by Hodder Education
Authors: Mike Crundell, Geoff Goodwin and Chris Mee. This book is according to the
syllabus, so you don’t need to worry about skipping anything
2. Physics in Context by Jim Breithaupt
3. Cambridge A levels by David Sang
4. Finally solve as much past papers as possible!
Website:
This one has answers to a lot of MCQs, so you might like to check that out as well:

Explanation:
https://www.cyberphysics.co.uk/practical/skills/micrometer.htm
The main scale reads 2.5 mm. Please note that unlike in the above website, there are
markings on both the top and bottom and each mark is separated by 0.5mm
,Side scale is at 9, so total reading: 2.5+9*0.01 = 2.59 mm
Reading without the wire (this accounts for any zero error) = 14*0.01 mm= 0.14 mm
So, diameter = 2.59-0.14 = 2.45 mm

, Explanation:
Pressure at the point marked blue for the left sided tube = P + g * (rho)w * hw
Pressure at the same point for the right sided tube = Pa + g* (rho)m* hm
Since pressure at the same heights are equal, P + g* (rho)w * hw = Pa + g* (rho)m *hm
Pa = P + g* (rho)w *hw - g* (rho)m * hm
