Read the two sticky threads and the "Thank you Asivad" thread. That "thank you" thread only has around 380 pages, so it should occupy your time until you can secure an ITA.
Hi - With the CRS score of 463..its most likely that you will getting the ITA soon. In the meanwhile you can get ready with the documents you will require post ITA like
1. CIC approved medical centres near your place to get the Medicals done
2. Process to get the PCC from all the countries you has stayed from past 10 years.
3. Scan copy of required documents which you will need to be submitted post ITA.
