So without any prep and just going through basics of Quantitative, I attempted a practice test and scored a meager 380.
I am targeting for 700+ and have no exact deadline or date in mind for test. But hoping to take the test in next 4-6 months time frame.
Looking forward for some advice and help, how to start and do good on the exam?
Thank you for all the advice and help experts

Now that you have taken a sample test to assess your current level, you must consistently prep for the test for about 2 months before taking any Mock test again.
The best way to start the preparation is to start the prep from the part that looks most appealing and most interesting to you.
If you think that Verbal interests you more then start with it from the official guide. There are various free online courses available so if you wish then you may refer to them as well.
If you think Quant interests you more then do the same with quant as well but please make sure that you are aware of the fact that the official guide doesn't represent the actual level of the GMAT exam which might be a little tougher than how Official Guide may represent it to be.
In case you are planning to take some expert advise then it would be very helpful as you will have both the direction and help to move forward.
Jump from 380 to 700 is very optimistic however nothing is a big obstacle of the roadmap is available and zeal to move in the right direction, with right efforts and with right attitude is present.
Hope things turn out to be in your favour soon. If you need a demo assessment then we might help you with a free demo sessions to help you understand weakness and a sound plan to work in the right direction.
Hope this helps!!!
