The CFA Institute explained the current restrictions on passing the exam

Earlier the CFA Institute suspended access to the website and account management in Russia due to the international blocking of financial transactions.

The CFA Institute has officially explained the restrictions on exams for citizens of the Russian Federation:

Access to the CFA Institute website and account management has been suspended in Russia due to the international block on financial transactions. As a result, members will not be able to access their CFA account and candidates will not be able to register, change exam appointment, or request a refund at this time. If a candidate moves outside of Russia, he or she will be able to access or create their CFAI account and register for a chosen exam unless working for one of the sanctioned institutions. The suspension affects candidates and members residing in Russia, not Russian nationals.Access to the CFA Institute website and account management has been suspended in Russia due to the international block on financial transactions.
