I've done an offline course(jamboree), it was months ago. I got out of practice because of work.
Now I've registered for trials at 1)theeconomist( did Verbal - CR) seems pretty good.
so My maths is pretty below average generally, I have studied it like 10 days. completed studying material and OG, but that's not enough so far because I got 13/31 in a practice test that too time went way beyond.
I also have trials of 2)
magoosh( not sure why there's so much hype about it, didn't find it any good at least the trial)
3)Egmat
4)exampal
5)empowergmat
6)mathrevolution
so I want to relearn and revise english from basics. and revisit the following topics in quants
(1) Ratio and Fractions, (2) Geometry, (3) Functions, (4) Permutations and Combinations, (5) Probability
Which courses you guys have taken? I plan to give gmat in 1.5months
Budget is not an issue I can buy any courses.
