+## Other advice for this unit
+
+### Get more exam papers on OneSearch
+
+- You can access up to **6** more papers with this method (You normally only get the previous year's paper on LMS in week 12).
+- Either [search "Communications" and filter by type "Examination Papers"](https://onesearch.library.uwa.edu.au/discovery/search?query=any%2Ccontains%2Ccommunications&tab=Everything&search_scope=MyInst_and_CI&vid=61UWA_INST%3AUWA&facet=rtype%2Cinclude%2Cexampaper&lang=en&offset=0)
+- Or search old unit codes
+  - ELEC4301 Digital Communications and Networking
+  - ENGT4301 Digital Communications and Networking
+  - ELEC3302 Communications Systems
+  - Note that ELEC5501 Advanced Communications is a different unit.

+### Tests
+
+- A lot of the unit requires you to learn processes and apply them. This is quite time consuming to do during the semester and the marking of the tests will destroy your wam if you do not know the process (especially compared to signal processing and signals and systems), I do not recommend doing this unit during thesis year.
+- This formula sheet will attempt to condense all processes/formulas you may need in this unit.
+- **You do not get given a formula sheet**, so you are entirely dependent on your own notes (except for some exceptions, such as the $\text{erf}(x)$ table). So bring good notes.
+- Doing this unit after signal processing is a good idea.
