Hope it helps ......

Plz mark as brainliest........

Answer 2

heymate!

here are a few topics from which the questions have come in previous year papers:

1.BIOLOGY

• mendelian experiment

•reflex arc and neuro.

•asexual and sexual reproduction

•hormones

•dams and garbage management

•biodiversity (10% law and tropic level)

•evolution

•vegetative reproduction

•acquired and inherited trait

•placenta( most important because it has come in previous consecutive years)

2. CHEMISTRY

•Ethanol and ethanoic acid (very important topic)

•amphoteric oxide

•Names and formulas of all the salts

• IUPAC

•Decomposition reaction

•Extraction

•Esterfication and saponification

• periodicity and electron dot structure

• cleansing action of soap

3.PHYSICS

•Numerical: power,heating,series and parallel combination , mirror and lens.

•VI graph

•Vision problem and correction

•Colourful world: Intext and ncert questions only

•Factors on which resistance depend

•Dispersion of light

• refractive index

THESE TOPICS ARE ENOUGH TO GET 70+

HOPE IT HELEPD YOU!

BEST OF LUCK FOR YOUR PAPER^_^
