Is it real to prepare for ACT for a month or two?

Test Preparation
1

I already had SAT and got 1710, but dont want to write new one, so the question: is it real to prepare for ACT for a month or two to get 27 and more?
I’m an international student and reading section is the hardest for me, while my math skills are good.
P.S any suggestions?

I prepped for 3 weeks before (about an hour each day) and got a 34. I bought the ACT prep when i registered online. I thought their questions were harder than test. REALLY helped me in reading and english where I got a 35 & 36. It will tell you your weaknesses and devise some practice tests, etc. May be worth checking out.

Did you take any other similar international exams before?
P.S thanks for advice)
