Hi There

Juggling between work and studies is tough so you need to define a significant time for your GMAT preparation.

Sometimes taking few days off work for preparing for the GMAT can help a person tremendously. If you have time this may not be a bad idea. Take practise GMAT tests to see how you are doing. If you cannot do that don't worry. What might work instead is to set aside 1-2 hours at night on weekdays and major part of your weekend to study and prepare for GMAT- in this case we will suggest a good 3 months preparation.

However we recommend you to keep taking practise tests to gauge your performance. It will help you in identifying your weak areas and you can focus on them accordingly.

There are various ways you can use to practise for your GMAT. It could be combination of online classes, coaching institutes, practise books and even smart phone applications. Having this combination will be giving you access to different styles and it won't be monotonous for you. Assuming you are aiming for top schools a score above 700 on the Gmat would be advisable.
