RRB NTPC പരീക്ഷക്കായി തയ്യാറെടുക്കാനായി പഠിക്കാനുള്ള പുസ്തകങ്ങളെ പറ്റി ചോദിക്കുന്നവർക്ക്, എനിക്കറിയാവുന്ന കുറച്ച് നല്ല പുസ്തകങ്ങളുടെ ലിസ്റ്റാണ്:
GK പഠിക്കാൻ ഇതിനെ വെല്ലുന്ന മറ്റൊരു പുസ്തകം ഞാൻ കണ്ടിട്ടില്ല:
Lucent's GK- amzn.to/3lSAg7T
എന്നാലും, ഏകദേശം അതിനോടൊപ്പം തന്നെ നിൽക്കുന്ന മറ്റൊരു പുസ്തകമാണു
Arihanth GK - amzn.to/32dDSKf
QA പഠിക്കാൻ ആയി- This one will help you: amzn.to/32a4sEc
Reasoning പഠിക്കാൻ ആയി മുൻ വർഷ ചോദ്യങ്ങൾ practice ചെയ്യുന്നതാണ് നല്ലത്.
This one will help you: amzn.to/38PXMwe
Current Affairs - 2019
amzn.to/35bBV2p
Current Affairs- 2020 till June
amzn.to/3m00y88
ഇനി ഏതൊരു പരീക്ഷാ തയ്യാറെടുപ്പിന്റെയും നട്ടെല്ല് എന്ന് പറയുന്നത് മുൻ വർഷ ചോദ്യങ്ങൾ വെച്ച് നമ്മൾ എത്ര മാത്രം തയ്യാറെടുത്തു എന്നതാണു.
അതിനു എന്നെ ഇത്ര മാത്രം സഹായിച്ച പുസ്തകങ്ങൾ വേറെ ഇല്ല. I would say these are the best:
QA- amzn.to/3gLUOLO
GK- amzn.to/3iVBhKY
Reasoning- amzn.to/2DzxN0y
English- amzn.to/3flQuCJ
For writing mock tests- ഒരു വർഷത്തേക്ക് Testbook എന്ന വെബ്സൈറ്റിലെ എല്ലാ പരീക്ഷകളും. മര്യാദക്ക് ഉപയോഗിക്കാമെങ്കിൽ നന്നായി മുതലാക്കാവുന്ന ഒരു സ്‌കീമാണ് ഇത്: amzn.to/3012VgV
