Limit on Tier 4 Visa Duration

Hi,

I came to the UK in September 2012 and was on a Tier 4 visa for 4 years till Sep 2016, studying for my undergraduate degree (BEng). I have been on a Tier 2 (General) visa since Sep 2016 till now.

I want to go back to university and study for an MBA. The course also involves a year long placement which makes it 2 years in duration. I recently learned that there is a limit on how long you can be on a Tier 4 visa. Can I go back on a Tier 4 visa for 2 more years?

Thanks for your help.

Regards,
