IS OG sufficient for a decent prepation,otherwise whats th alternative

Hi and welcome to GMAT Club Larbi!

Official Guide provides something you can't get anwywhere else - official questions but little beyond that. It is not a course or a guidebook or anything but a collection of questions. It does have some random math rules, formulas and some tips but barely enough - take a look here for some ideas: https://gmatclub.com/forum/the-definiti ... ml?fl=menu

Honestly, it really depends on where your first diagnostic score was at. If you scored about a 650-680, then just using those materials will probably propel you over 700. HOwever if you're in the 550 range? probably not

there are a lot of free GMAT materials, so look into those as well. check out your local barnes and nobles (if american) for free materials

Hi Larbi,

Many Test Takers who use a 'book heavy' study approach end up getting 'stuck' at a particular score level, so you'll likely end up needing to invest in some non-book resources. The OG books are great sources for practice questions, but they're not designed to teach you Tactics, patterns or the little 'secrets' behind the GMAT - for those, you'll need Course-oriented materials. To that end, you should work on the OG a little later on in your studies.

Since it sounds like you're just beginning your studies, then it would be a good idea to take a FULL-LENGTH practice CAT Test; you can take 2 for free at www.mba.com (and they come with some additional practice materials). If you want to do a little studying first, so that you can familiarize yourself with the basic content and question types, then that's okay - but you shouldn't wait too long to take that initial CAT. That score will give us a good sense of your natural strengths and weaknesses and will help provide a basis for comparison as you continue to study. A FULL CAT takes about 3.5 hours to complete, so make sure that you've set aside enough time to take it in one sitting. Once you have those scores, you should report back here and we can come up with a study plan.

I'd like to know a bit more about your timeline and goals:
1) What is your exact Test Date?
2) When are you planning to apply to Business School?
3) What Schools are you planning to apply to?

When it comes to GMAT prep, different study materials work well for different students. So, regarding your prep books, my best advice is to give them a shot. Some students find that prep books fit their learning needs and “study style” well. The important thing is to objectively evaluate your progress so that, in the event that the prep books aren’t meeting your needs, you don’t end up overinvesting time in resources that aren’t working for you. Thus, if after 4 to 6 weeks you find that you are not making the improvement you need, consider changing up your study routine. Certainly that change would not have to be anything drastic, but you may consider using a self-study course. Self-study courses typically provide detailed study plans and have granular analytics, so you can easily track your progress as you move through the course. The ability to track your progress will keep you more engaged, and you’ll be able to more accurately forecast when you’re ready to take your real GMAT.

If you decide to go that route, GMAT Club has reviews on the best courses for GMAT prep.

Also, since you are just starting out, consider taking a practice test from MBA.com to determine your baseline score. Based on that score, you may have a better idea of the necessary time and resources you need to achieve your GMAT goal score.
