Hi there!
It's great to hear that you're starting your GMAT prep! Your choice of using the GMAT Official Guide and
Manhattan GMAT for offline resources is solid, as both are highly regarded.
Regarding online resources, here are some thoughts:
1. Target Test Prep (TTP): TTP is known for its comprehensive quant review and structured study plans. If you're looking for a strong focus on math and have the budget for it, TTP could be a great investment. It wouldn't be redundant to use it alongside the OG and
MGMAT, as TTP can provide deeper insights and practice specifically for quant.
2. Magoosh: Magoosh offers a more budget-friendly option with a good range of video lessons and practice questions. It’s a solid choice if you want a broader overview and additional practice without breaking the bank.
3. e-GMAT: e-GMAT is particularly well-regarded for verbal preparation, especially for non-native English speakers. If you feel you need extra support in verbal, this could be a worthwhile option.
Since you're already investing in offline resources, you might consider starting with TTP for its depth in quant and then supplementing with
Magoosh or e-GMAT based on your specific needs in verbal or additional practice.
Ultimately, it depends on your strengths and weaknesses. If you feel confident in quant and need more help with verbal, e-GMAT might be the way to go. If you want a comprehensive approach, TTP combined with either
Magoosh or e-GMAT could be beneficial.
Best of luck with your preparation! You're on the right track, and this forum is a great resource for guidance and support.
