Dear all,

I am planning to give GMAT after 5 months but i have never come across any material ahead. I would like to know these things:
1. How should i start my practice session?
2. What books should i purchase?
3. Does online resource really help? Which did you find helpful?
4. What is the normal time that we need to allocate for studying GMAT?

Would love to hear your experience. Thanks in advance
