Mohammed,
If you already have your exam scheduled for July 22nd, then I recommend that you start right away. You have 7 weeks left to study until then. I believe that if you can invest 3-4 hours of study every day, then you should be able to make it.
Watch all lessons E01.xx, then go to E03.xx - E12.xx. Also watch E70.xx. If there is time left watch the rest as well.
On average you are going to have to:
- Read 1.5 Knowledge Areas in the PMBOK Guide per week
- Read 1.5 Knowledge Areas in the "Success" book per week
- Watch PrepCast videos from 1.5 Knowledge Areas per week
It's a lot of studying, but if you set you mind to it, then you can still do it.
