Yes, solving OpenTuition questions can be a valuable part of your last-minute preparation for ACCA exams.
While they’re a great resource for understanding concepts and practicing questions, it’s important to combine them with other study materials to ensure comprehensive coverage.

Here’s a suggested approach for your final month:

Review Core Concepts:
Revisit the key topics, especially those you find challenging.
Use the ACCA Study Hub or your preferred textbook to solidify your understanding.
Practice, Practice, Practice:
Prioritize BPP or Kaplan Questions: These are often considered more exam-standard and can help you get accustomed to the exam format and difficulty level.
Use OpenTuition Questions as Supplementary: These can provide additional practice, particularly for topics where you need more exposure.
Focus on Weak Areas: Identify your weaker areas and dedicate more time to practice questions on those topics.
Time Management:
Practice answering questions within the allotted time to improve your efficiency.
Use past exam papers to simulate exam conditions.
Mock Exams:
Take as many mock exams as possible to assess your readiness and identify areas for improvement.
Analyze your performance in mock exams to pinpoint weaknesses and focus on them.
Seek Clarification:
Don’t hesitate to ask questions on forums like Reddit’s r/ACCA or consult with tutors or fellow students.
Understanding concepts thoroughly is crucial for success.
Remember:

Quality Over Quantity: Focus on quality practice rather than quantity.
Consistent Study: Dedicate consistent study hours to maintain momentum.
Positive Mindset: Believe in yourself and stay positive.
