35 is a decent score in biology although it is understandable it may be a disappointment if you were aiming higher.
A 90+ ATAR is definitely still possible if you do well in your year 12 subjects.
The aggregate needed for a 90 ATAR in 2023 was 156.5 If you got 35 in all 6 subjects you would have a total of 147 which is slightly below that.
If you get 2 39s, 1 38, 1 35 and 2 30's that is 157 and more than a 90 ATAR. However one of those non 30 scores must be an English. Also if you get higher scores you can compensate for lower scores in others.
