Worried about my diagnostic score

After going through week 1, the end of the week mentions taking a diagnostic test.

I got a measly 287 (142 V, 145 Q) - is this normal?
Should I be worried? I plan to give the GRE next month and I’m going through PrepSwift currently

I was hoping to get around 320 for my GRE General test next month, so this feels a bit disheartening

How much time do you have per day to study?

I have taken 3 weeks off in preparation for the test (March 25 - April 1) and then 1 week leading to my exam on April 25 (April 15- 24), during which I can focus upto 12 hours on it.

On the other days as I have work, I can dedicate 2 hours confidently and remainder would be ad-hoc (Like doing vocab/quant mountain during commute)

12 hours is not realistic or healthy, try and do around 6 to 8 per day.

On the work days just focus on “memorization” → vocab and quant mountains and flashcards

It’s gonna be difficult, but it’s possible. However if you find that it’s taking a long time for your foundation to improve you might need to push your test back a bit.

I would go back and review your arithmetic foundation and then resume the study plan.

Thanks for your advice!
I had initially booked the exam for April 25 solely because there was an offer ongoing here that would provide a 25% discount on the GRE provided I book my exam before April 30.

I’ll try my best to get everything done and focus on it but in worst case I’ll postpone it by a week or so.
