Can I proceed with Module 3 or 4 without completing 1 and half of 2?
No. The reason for this is that the results and studies / exercises will be helpful tools for the advisor in their interaction with you on your situation. The danger with a series like this is the temptation not to complete it, but skip to the bits of more interest. Even if you do communicate with an advisor before all sections are done we encourage you to complete them all.
