I am an independent professional now

I recently cleared the very popular 98-368 certification exam. The exam is famous because if one clears it, his career takes a leap ahead in the future. As my career was facing major roadblocks, i decided that i should go ahead and make a niche for myself. So i decided to give the exam but the million dollar question was how will i prepare for the same. So i decided to do some search online and landed on this amazing website that had unlimited supply of Mobility and Devices Fundamentals practice questions that still remain with me even after the fact that i cleared the exam with a good score.
