You’re probably going to
hate this.
We have only two goals on quant in Week 1:
1. Ensure that you NEVER make sloppy errors.
2. Check on your arithmetic and algebra foundations.
Here’s why:
1. On an adaptive test like the GMAT, careless errors can DESTROY your score. To learn why, check out
this video on GMAT time management (6 mins.) or
this one on score-killing errors (59 mins.). These videos were made for the old, pre-2024 version of the GMAT, but the punchlines are still spot-on.
2. If you’re unhappy with your quant (or DI) score, you’re probably making careless errors. And you probably don’t pay enough attention to them.
3. Arithmetic and/or algebra are embedded in nearly every quant (and quant-based DI) question, and if those fundamentals are shaky, you’ll be in trouble.
I know: this isn’t sexy. You probably won’t enjoy this. But if you perform well, the homework will get more interesting next week.
How to approach quant homework1.
Time each set, but don’t rush through. Do every set with
test-like intensity, but don’t impose an artificial time limit -- at least not yet.
2. When you’re finished, please do NOT review your errors at all just yet. On the day you do the homework, just input the results into your
error log, and walk away. (We’ll say more below about how and when to redo the questions you missed.)
Week 1 quant homework
By design, these practice sets are mostly short, and
they should FEEL easy. So you shouldn’t make any mistakes at all, right? Um... right?
1. Watch
this video (34 minutes) on how to approach GMAT quant and data sufficiency.
2. (Optional, but recommended) Videos:
how to get better at studying for GMAT quant (8 mins) |
GMAT arithmetic (49 mins) |
GMAT algebra (70+ mins)3. (Optional, but recommended) Do a set of 10 general systems of linear equations, which you can generate
here. If you’re not efficiently getting 100% of them right (in less than 15 minutes per set of 10), keep doing sets of 10 until you can ace them.
4. (Optional, but also highly recommended) If you’re rusty on quadratics factoring, solve
this set of 10 basic quadratic equations. If you need more practice, you can generate more worksheets
here; select as many "Quadratics --> simple factorable" exercises as you need.
5. A set of 25 sub-555 algebra problem-solving questions, available
here. Yes, they’re easy. That’s exactly the point – please don’t make any sloppy mistakes!
6. Official Guide Problem Solving #1-25
7. A set of 25 sub-555 arithmetic PS questions, available
here 8. (Very, very optional) Quant section only from the
GMAT Club tests or another NON-official source (save the remaining mba.com exams for later!)
What to do AFTER completing a quant homework set- 1-3 days after completing the set, redo your errors from scratch. Do your best to “wash your brains” and pretend that you’ve never seen the questions before.
- If you get most of the questions RIGHT the second time: you’re probably making careless errors, and fixing them needs to be your #1 area of focus. See below for some videos that might help.
- If you miss a question twice, don’t overreact. Obsessively studying individual questions drains a TON of your study time – if you miss a particular question, you’ll probably never see anything quite like it again. So focus on GENERAL takeaways on how to improve -- don’t spend hours memorizing steps for individual questions.
- For more on how to interpret your results, see the next post in this thread.
