Study plan advice: 6m to prep - makes sense to start now?

Hello everyone,

I am new to the forum and I have a novice question

I aim to take the GMAT in the near future but I have no rush for it - concretely, let's say i would like to do the test in 6/7 months.

I was wondering if it makes sense to start preparing now at 'low intensity' (few hours per week), and then start putting in some hard work in the 3 months leading to the test? Or low-intensity + too in advance wouldnt be that useful (I would 'forget' things)?

I was planning to start anyway with some quant and verbal basics (MGMAT Math Foundations and GMAT ULtimate Grammar) and then move on with more 'advanced' books after summer holidays (when actually) I will not spend time on any book

Would be great what suggestions others have for people in my situation - does starting now make sense or the only effective way to go is 3/4 intense months?

thanks in advance
