I have an average - low iq, as well as being diagnosed with autism, is continuing astrophysics even possible?

For context I am in 2nd year 1st semester of my physics program with my exams coming up in about a month and a half, my grade average at the moment is around 73% which by the UK/EU standard is considered pretty good. I deferred for one year due to some mental health troubles which were causing me to fall behind in my studies. It was also during this time I got an autism diagnosis along with an iq of around 100(I cant remember the exact number as I don't have the files on my right now) with the only thing special about me was a very high score on the verbal/ language part of the test.

Upon researching if I am capable of completely this degree I've come across that the average is around 130 for astrophysics, leading to me becoming worried as to whether ill be able to completely my degree and go with my original plan of obtaining a masters in a more specialised field of study(in the realm of physics of course).

I've noticed that while I can understand conventionally easy topics like most of calculus 3 along with the basic of thermodynamics I'm now beginning to struggle with conceptually wrapping my head around topics such as more advanced vector calculus and electricity and magnetism(think volume integration and solving problems using circuit diagrams).

Is thus a sign I'm starting to reach my intellectual limit for understanding physics and signalling that I should give up or am I overthinking all this.
