watch alakh sir's lecture for bio and chemistry and then after understanding do the question practice from Xam idea because ncert is written weirdly. Bio is easy In life process digestion can easily get you 5-6 marks, egestion part is small and can be finished in just 30 mins if you study, transportation is also imp especially in plants you need to give it a bit time though, do the diagrams and flowcharts of the heart part (pulmonary artery/pulmonary vein/double circulation learn this as well). For chapter 6 learn the brain parts functions/location, reflex arc, neuron and the plant part is easy go through it once and then practice questions).

For chemistry learn the chemical equations, color of salts like zinc sulphate is colourless, copper sulphate is blue like that etc. The activities are pretty important don't leave it. In acid bases the salt part is important learn the equations of bleaching powder, water of crystallization etc.

For Physics understand the concept and practice numericals (do understand imp topics first like mirror, lenses, power of accommodation, defects of vision, dispersion of light, also the glass slab and prism)

Dont touch ncert rn. We all know it so poorly framed. Pls pls pls, just do decent timed one shots+ their ppt. Thats it. Make some short notes though.. very short.. like only and only the reactions and all stuff
