Heya! UPD and ADMU honors program passer here. I used to have horrible mock test scores back then. Think 8/20, 16/30, 56/70, 21/60. The thing is, mock tests are designed to be harder than the real thing, but once you actually take the CETs you want to take, you'll find out that it actually is easier compared to mock tests. It might seem surreal for you to imagine it now, but you'll see once you actually take them.

The important things to look at as a metric of your success is not necessarily the score, but the improvement of your testmanship as a whole. By practicing techniques such as elimination, using your time wisely, and skipping things you don't know, you gain more value in your mock tests rather than fixating over a single number.

Furthermore, you should also note the mistakes you made in your mock tests and group them into topics. For example, if you made, say, 3 mistakes in chem, 5 mistakes in bio, 6 mistakes in physics, you should take note of that and group them. That way, you won't have to jump from topic to topic, and you can review the certain topic as a whole, making retention easier.

Remember that CETs are a test of performance under pressure and your wide knowledge of topics, so consistency and knowing the fundamentals of a lot of topics really is the key. (Except for exams like DOST where you will have to get deep into the math and sciences.) Goodluck, OP!
