Here's my two cents on how to prepare for the GMAT Online exam in 2020. But before we begin, some background on me:
Background: Took my first attempt straight out of college and scored a 690 with a month of prep. Now here I am two years later and have re-started my prep. It's been 3 months now and I'm managing a score around 720 in my mocks. Here's the strategy I am using while working full time at a consulting firm.
Strategy tip #1: Focus on official guides. I solved the OG, OG Verbal, OG Quant and OG Advanced and have also given 5 out of the 6 official mocks (With a 10 point increase in each try). I found that deep-diving into OG question molds your thinking according to the way GMAT wants you to think.
Strategy tip #2: Filter out the noise. A million test prep providers will bombard you with why their courses and materials are the best. Take a deep breath and consider them as 'extra' material once your done with the OGs.
Strategy tip #3: Spend a lot of time on creating error logs. Deep-dive into every incorrect answer and write detailed explanations about how and why you got it wrong.
Study Plan:Following is a study plan I recommend for working professionals:
Weekdays:Morning: 20-30 Official Questions (Alternate between quant and verbal each day) + Review incorrect questions and update
error logEvening (post work): Identify weak points in
error log and browse theory/strategy on those question types
Weekends:Saturday: 30Q + 30V questions + Review + Theory
Sunday: Mock test + Review
