The last Veritas Prep CAT I took I got a 34 on Verbal and a 46 on Quant. Yes I meant the online OG questions that you get with the OG Book. My big question for you is: how is your verbal? Yes, dabble in math to stay sharp, but you don't have a lot to improve there. Here are a few reasonably challenging Magoosh Quant question: Here's a lesson, the depth of which may intrigue you:

If you feel that you need another 500 questions, some extremely challenging, then certainly Magoosh would provide more practice. I would recommend Magoosh if you needed more math practice, but it's not clear to me that you do. Everyone once in a while, they will throw you a question that's confusing because it's so out-of-the-box, but for the most part, if you are acing math on the official site, I don't know that you need to sharpen your math skills much more. Here's the thing: for anyone really good at math, GMAT Quant really isn't that challenging. Nobody knows what you mean if you call them 'Wiley'-those are the OG questions, in fact, the exact same Quant questions that are in the OG, just on the computer. When you say 'Wiley,' do you mean the official practice that is a companion site to the GMAT OG? Those are official questions! Those are absolutely the best questions available, and the most GMAT like. I would say that Veritas has very good material, as does MGMAT. I see that no one has responded, so I will respond. Is Magoosh a good resource for quaunt? I don't really need the videos, just the question bank - I am generally good at self-study and have been using MGMAT. I don't want to waste time on something that won't sharpen my Quant skills.

Is Wiley a good source for Quant practice? I take a 15 question practice every night after my verbal prep and I get almost 15/15 or 14/15 right. They are almost as easy as the 600-700 questions or sometimes sub 600 questions on Gmatclub. My issue is that the questions that are even marked Hard on Wiley are not at all challenging. I moved onto verbal and finally decided to use the Wiley question bank to keep my Quant practice going on as I concentrate on verbal.

On the Veritas question bank + Gmat club problems that i solve my average stands at 70% for medium and hard problems. I've basically brushed up all the concepts in Quant and now have moved over to Verbal. I've been using GMATClub's and Veritas Prep's Quant question bank to practice for the past 1.5 months.
