Dear Aspirant,

Remembering abbreviations is really really haunting and it isn't that easy as it looks here are few things you may consider to remember abbreviations:

• At first Learn what does the abbreviation you are facing means : it's is always recommended to remember the abbreviation full form rather than abbreviation itself since words reduces almost most of the complexity than the characters.
• Try making mnemonic , yeah it's fun to do this and found to be most efficient all times.
• Mix it up : Try to remember the words and stop worrying about the acronyms as many words in your brain can generate an approximate and accurate full form for the abbreviation asked without your knowledge.

Hope this helps you out
All the best
