Probably not, and it's not your fault. This has got a scientific name, and it's called, "the forgetting curve". Your brain needs to repeat things regularly to remember them.
To maximise your chances of a higher grade, revision should be something you do in years 10 and 12 too. It's like running a marathon. You can't start running 26 miles a few weeks before the race because you need to build up the number of miles your body can cope with over a longer period of time. Exams are a marathon for your brain.
What you remember from your lessons:

After the lesson

The next day

The next week

The next month
Smart Revise was built to fix the forgetting curve. Quiz mode presents you with a never-ending playlist of multiple-choice questions you can dip in and out of as you like. Only got a few minutes while you are waiting for the bus? No problem, open Quiz on your phone and put it away again when the bus arrives. Smart Revise helps you remember more of what you have been taught.
Set the topic filters to the topics you want to focus on. These may be controlled by your teacher if you have joined a class.
Research shows it is better to mix questions from different topics. You can focus on one topic at a time, but this can be less effective.
Choose Quiz and answer the questions aiming to get them all right three times in a row, but not knowing when a question might reappear.
You can see how well you are getting on using your personal usage and revision reports.
Smart Revise will tell you!
Smart Revise will analyse your data and each week set you an achievable goal.
That's the basics but if you want to learn more about Quiz, this is how it works...

Interleaving
Means mixing questions from different topics together. It has been shown to help memory retention more than blocking - looking at just one topic at a time.
Pseudorandom
Means a deterministic but seemingly random order. Random would mean the current question could possibly appear as the next question too. Pseudorandom order prevents this happening.
Spaced learning
Means a period of time elapses between seeing the same question again. Spaced learning has proven to enable the best memory retention effectively beating the forgetting curve.
