GMAT Please help with my future 3 months study plan

Hi everybody,
Started my preparation with a cold 440 Q32 V19 (without even knowing how DS works)
Then I did 2 weeks using an online platform
Another mock 500 Q39 V21
then did another month with the same online platform but I relized I wasn't learning anything. So I decided to start reading all the manhattan and practising on only one question/topic at once and only with this I saw some improvements, especially in verbal.
I practised a lot (maybe too much) using the gmat club and OG for 3/4h a day (I realized It's too much) but I didn't use an error log. (assume my bigget mistake)
Today I took my third mock after 2 months of the new "plan" and scored 560 Q41 V26.
Felt that quant was too easy in comprarison to the questions I usually practised on and Verbal....... I did tons of CR and I was PERFECT on 600 level , 90% on 600-700, 75% on 700 level (Only OG)
SC left behind but still decent and RC did only 10-15 texts , especially the last 600-700 level RC's I got 5/6 or 6/6 and so on (max one wrong per text).
During the today mock I felt : QUANT too easy, I could do some DS in 20 sec and I felt very fresh and with much time available .
VERBAL: I realized I got used to do one question at time but I definitely wasn't able to maintain concentration and mental "freshness" for 65 min. (i got wrong some ridiculous CR and the letters of RC texts felt flying).

I NEED TO CHANGE MY STUDY PLAN in a more strategic way and studying less hours per day (very often I ended up studying 5-6 hours a day, or thinking always to the gmat, even when out with my girlfriend :lol: )
In june I'll have my final exams so I definitly need to reduce gmat daily time to max 30-60 min and then in July I'll start my intership (8 hours a day) where I hope I'll be able to study at least 2 hours a day before going to work. I would like to take the gmat in September max October in order to send my application in R1.

MY GOAL : 650+ (because I will apply to Master in Management 90% surely)
MY DREAM: 700 and I think I could achieve it if I find the perfect strategy for me

MY DREAM SCHOOLS: as everyone else out there LSE LBS HEC .......
more or less ACHIEVABLE : escp , Ie, Esade, Imperial (halfway dream-achievable I think).....
