in inorganic chemistry mostly questions are with signs and even if doing periodic table with exceptions and all my mcqs are getting incorrect leading negative marking!Any solution?

ANUVAB DAS 23rd Aug, 2020

Hi,

You need to do the following to prepare for inorganic:

  1. Make a list of all the exception of a particular block elements ( suppose d block).
  2. Put that list up on the front wall of your study table.
  3. Watch them daily. No need to read. Just watch them in a regular basis.
  4. Find out problems ( that's going to a tideous job indeed) related to those exception and solve them. Don't forget to take help from your prepared list while solving problems.

You will soon be a master of inorganic. Don't leave inorganic problems in NEET. Inorganic is a highly scoring subject. You just need to practice a lot of questions to grasp all the information of inorganic.

Best of luck ! I believe you will try your best.

My Boards Result Is English-81, Maths-54, Physics-54, Chemistry-50, Biology-66 & Add-64. I Want To Pursue My Studies In BioTechnology & Also Get Prepared For UPSC Exams. Whats The Best Thing I Can Choose? From Where? (Which Institution) (For A Lower Middle Class Family) Other Alternatives?

ojaswiyolo Student Expert 17th Jul, 2020
Hey
If you are interested in Biology you should surely choose a good institution. Since you have mentioned about budget friendly institutions so I will recommend you to try to get admission in a Government College. You can try CUCET to get admission in Central Universities by giving the entrance exam or you can apply for admission in Government Colleges like Asutosh college etc which have biotech. If your score is not allowing you to get selected in these places and you can spend a bit more you can try LPU or Amity or Sharda or KIIT.As far as UPSC goes, taking an online course from Unacademy is as good as an offline tuition. They are good at providing accurate syllabus and is not really expensive either.
I hope this helped.
