What is difference between
Class 10  Maths+Science (SA2) AND Class 10 Maths+Science (PCB)
Generation Next (verified owner)
In Class 10 Maths+Science(PCB) covered whole syllabus of Maths and Science While in Maths+Science(SA2) Covered only Syllabus of Summative assessment2.
mera kal exam he aur muje sab samaj me aaraha he
