CBSE Grade 10 Mathematics Starter Kit

Must-do topics

• Real numbers (HCF–LCM, decimals test)
• Polynomials (zeros–coeffs, quadratic graphs)
• Pair of linear equations (elimination, consistency tests)
• Quadratic equations (formula, discriminant)
• AP & GP basics
• Similar triangles (AAA/SAS/SSS, Pythagoras)
• Trigonometry + applications (identities, heights/distances)
• Circles (tangent properties)
• Surface areas & volumes (composite, frustum)
• Statistics (mean/median/mode, ogive) & Probability basics

Top traps

• Forgetting discriminant check before solving quadratics
• Mislabeling hypotenuse/opposite in trig Qs
• Copying wrong formula (CSA vs TSA)
• Median from ogive mis-read
• Units mismatch (cm² vs m²)

Time split

• Algebra 30% | Geometry+Trig 40% | Mensuration+Stats 30%
• 5–6 markers → 10–12 min each with clean steps

Last-48h checklist

• Re-do 2 quadratic sets + 2 similarity proofs
• One full mixed paper timed (3 hrs)
• Formula skim (trig identities, SA/volumes)
• Revise construction steps cleanly
