Hello!
Can someone please help me with the 'replacement concept' in mixtures and alligations? I have my exam in 3 days and I just realized I dont know the concept at all. Also, I have tried searching for the tips and tricks on the forum, couldn't find them.

It'll be great if anyone can help! :)

Hi Diksha23,

To start, 'mixture' questions are relatively rare on the GMAT (you will likely see just 1 on Test Day - and it might not even test you on the specific issue that you are asking about). This is meant to say that if there are any of the larger categories that you're not great at yet, then your time would likely be better spent on those areas.

In these last few days, you should limit your studies to general practice and light review (NO CATs and NO 'cramming') - you would be better served by getting some extra rest so that you can go into Test Day calm, clear-headed and ready to work.

If you have a specific Quant question that you'd like to discuss, then you should try posting it in the appropriate Quant forum
(here: https://gmatclub.com/forum/quantitative-7/). It's also possible that your specific question has already been discussed, so you should try "Googling" it.

GMAT assassins aren't born, they're made,
Rich
