How would you recommend studying from these textbooks?

This is more of a subjective Q so my approach might not necessarily work for you but hopefully it gives a starting point.

1. Go to chapter review and have a skim over the types of questions (this gives you a sort of guide to what stuff is more important etc because you'll be more focused on such details).

2. Have a read of the chapter (go through the content thoroughly, if you don't understand some parts, google it)

3. Make flashcards for important information (this is only for content heavy components so ideally Mod 3. Mod 1 and 2 is purely math)

4. Attempt all Qs under timed conditions (give yourself 1 hr in total and see how you go.)

5. Identify any weaknesses in attempting Qs (e.g forgetting direction or SI units/not going enough detail or providing quantitative analysis in explain qs)

6. Repeat 4-5 until you feel confident.

7. Go to the next Chapter, rinse and repeat.

You will be starting Kinematics so I HIGHLY suggest you brush up on trig a bit and get comfortable with cosine/sine rule and get familiar with vector addition/subtraction. This should be relatively straightforward and shouldn't take you that much time. The hardest part of kinematics will be the last dot point in the last IQ being the relative motion Qs, make sure you grind them.

Dynamics will be more mathematical but it shouldn't be much different, you'll be applying the vector methods to more classical examples such as objects on ramps (vector decomposition), pulleys (tension in rope etc), momentum, work, energy etc...... If you're decent at maths, this should be a trivial module.

Waves and Thermo will probably be the hardest or second hardest module because in this one, you'll have to start to get more qualitative questions which tend to screw over people but it shouldn't be too hard. Thermo might be hardest part but not really sure, definitely go ahead with this module in the holidays though so if you do struggle, you can get better early.

Electricity and Magnetism is probably the most enjoyable module. Its really just a wrap up and magnetism's barely covered so its just circuits really. If you've got through the other modules, then this is no different.
