Should I take Scaler Academy loan?

Generally not recommended. Starting your career with ₹3 LPA debt is risky.

Better alternatives:

  1. Use free resources (Striver, YouTube)
  2. Buy affordable options (LeetCode Premium, Udemy)
  3. If parents can afford without stress, then consider

Remember: Many FAANG engineers learned from free resources.

Coding Ninjas vs Scaler - which is better?

Coding Ninjas (₹15-30K):

  • Good for learning DSA
  • Self-paced
  • No job guarantee

Scaler (₹2.5-3.5 LPA):

  • Comprehensive with mentorship
  • Job guarantee (conditions apply)
  • Referrals to companies

Verdict: If you only need DSA, Coding Ninjas. If you need complete guidance, Scaler (if affordable).

Is GeeksforGeeks Premium worth it?

Usually not. GFG Premium benefits:

  • Ad-free experience
  • Some courses

Most GFG content is free. Spend that money on LeetCode Premium instead for better ROI.

How to stay motivated with free resources?

Tips for self-learning:

  1. Set daily targets: 2-3 problems minimum
  2. Join Discord communities: Striver’s, NeetCode’s
  3. Find study partners: Accountability helps
  4. Track progress: Use spreadsheet
  5. Reward yourself: Small wins matter
