Ahmed writes in. My name is Ahmed and I really enjoy your website and tweets. I just started studying for auditing and I'm kind of indecisive when it comes to using all materials and which materials I should use. I'm currently using 2011 Becker, but that is a mistake. I would not recommend it. However, you can probably get away with using old Becker materials. It's not the best practice, but it's not the worst either. If you have a 2014 BGC or whatever course, you could probably get away with Becker. But for the rest of them, I wouldn't do it. I would use July 2015 updates and later. The reason for that is because the FASB and the IASB are moving towards convergence and making FASB less different from IFRS. So, anyway, I would use July 2015 materials or later. As for those 2011 materials, if you have a fireplace or can have a bonfire, I would suggest using them as great kindling. Here in the canyons, it's a bit chilly today, which is why I have a t-shirt on. Subsequently, I started a fire. So, yes, don't use old materials (A) and as for which materials you should use (B), I'm biased towards ninja materials. I think they are amazing, but you might disagree. So, check out the Devereaux's materials too. Also, go to the other71.com forum and search for reviews of every review course you are considering. You'll see people posting a lot of pros and some cons about each course. By the way, you.
