Hi Ayush! Welcome to GMAT Club!

I too have motion sickness and it makes me feel dizzy when I read in a moving vehicle, so I can relate 100% to your predicament. I traveled for quite some time to and fro too and I found a unique way to deal with it.
Solve DS questions 
( I did so from the
GMAT toolkit.)
With nearly an endless supply of good quality DS question, and with the readability to see a large text of one question on your whole screen I could tackle the motion sickness. Also, DS questions often can be solved so to say "in your head" and do not require pencil & paper math.
This way I got better on a section that I was already good at. If you get bored of DS ( I doubt anyone could as it is the most fun section! You don't even need to get the final answer just to know that there is a unique one or not

) you can gradually proceed to SC - the section on the verbal with usually the least amount of reading.
Apart from the above two - you could also try audio-books. People with great voices read out things to you and it feels good to go through a material without the hassle of reading yourself. I always feel sleepy when I am read to and hence did not go down this road

Hope this helps. Let us know how you tackle this situation as definitely Bangalore traffic isn't going anywhere...

Hi,
Someone who works in Bangalore knows how hard it is to travel from office to home and how it is a waste of time(mostly) for those preparing for GMAT.
While some can read in a moving car/bus but some people (like me) tend to have a headache or vomiting sensation if they try to read anything by looking down.
So, I was hoping for some suggestions which can help me or others(travelling via cab or bus) utilise this time efficiently to prepare for GMAT and not waste the time just staring out the window.
Any suggestions/ideas would be highly appreciated.
Regards,
Ayush Anand.
