Kalsia Institute of Chemistry,K.I.C Chemistry(Physical,Organic & Inorganic) coaching classes by Shailesh Kalsia , B-Tech IIT and ex-HOD

It's about making chemistry learning as logical and systematic as mathematics.Learning inorganic from the maestro will be as simple as 2+2,and it will be great fun learning organic and physical, a sincere student will just love & appreciate the way in which chemistry will be taught here at K.I.C,it's my open challenge

IMPORTANT NOTICE
We at K.I.C have developed a highly unique scientifically designed chapter practice problems for INORGANIC CHEMISTRY.The problems range from single correct option,multi-correct options,matrix matching,Comprehension, integer type problems and exhaustively cover each n every concept of following chapters:
[Entire ncert is covered, n build up questions on ncert]
1.s-block
2.p-block(gp 13-18)
3.Hydrogen n it's compounds
4.Ores n metallurgy
5.d & f block
6.SALT ANALYSIS!!!!!
7.Co-ordination compounds
USP:Even if a student hasn't gone through ncert for these chapters( means he simply hates inorganic), then simply memorizing the answers to these problems he will b able to crack JEE-MAINS n JEE-ADVANCED(he will develop n aptitude for inorganic) and for those who have gone through ncert but don't have iota of an idea as to how to retain the concepts or how or what to cram(n understand) this is a lifetime opportunity for those. Mark our words, inorganic will become one of ur strong points!!!. Thses chapter practice problems(CPP's) will be available from 25th of March free of cost to students of K.I.C n token money will be charged for outsiders.

1.ENTIRE syllabus(For IIT MAINS N ADVANCED)
2.ONLY physical chem.(For IIT MAINS N ADVANCED)
3.ONLY organic chem.(For IIT MAINS N ADVANCED & BOARDS)
4.ONLY inorganic chem.(For IIT MAINS N ADVANCED & BOARDS)
It's a genuine attempt to tremendously improve upon and revise the fundamentals of subject i.e. S.B.N.B(Sidhi baat no bakwaas) n remember IT'S NOW OR NEVER.
