2. semiconductor
3. electrostatic 10)oscillations

In chemistry

1)mole concept 2)solutions 3)electrochemistry 4)periodic table 5)chemical Bonding 6)coordination and compounds 7)pblock 8) d and f block 9)goc 10) iupc and isomerism 11)alcohol phenols and ether 12)aldehyde ketone and carboxylic 13)amines 14)biomolecules 15)equilibrium 16)poc

I have missed some chapters and im scared I have given only part tests and around 3 full syllabus mocks im getting around 400 to 450.

Is there any way to improve should I give more mock or complete the remaining syllabus.

Tbh it takes me lot of time to understand so I would require detailed lecture and lots of question practice, on thes other hand I have fst of aakash starting so any help would mean a lot.

I need a rank below 1 lakh.
